Shots fired! Clint Eastwood's daughter calls her just-married pregnant sibling Morgan 'my evil stepsister' who is 'weird and fake' in social media outburst

It’s just two weeks since she celebrated her wedding at her father’s Carmel ranch but DailyMail.com can reveal that the family unity on display at Morgan Eastwood’s nuptials has now exploded into a very public slanging match.

The fight has pitted Clint Eastwood’s youngest daughter Morgan, 27, against her older half-sister Kathryn, 36, with director Kathryn accusing her younger sister of calling her ‘insane’ while dubbing her ‘my evil stepsister’ and ‘weird and fake’.

DailyMail.com can reveal Morgan’s mother Dina, 58, has also been drawn in – threatening Kathryn with legal action over her social media outbursts and being called a ‘greed [sic] money obsessed psycho’ in return.

The bitter feud appears to have ignited around the time of the wedding but had been kept under wraps until Kathryn, who lives in La Quinta, California, unleashed a string of furious Instagram posts last week lambasting her sister and stepmother.

The first sign of trouble came when Kathryn posted a video of herself dancing with her father at the wedding before they were interrupted by another guest.

'My siblings are weird and fake, inside and out,' Kathryn Eastwood claimed in an Instagram post less than two weeks after her half-sister Morgan's wedding on their father's ranch

A furious Kathryn wrote: ‘Got to dance with my dad for 50 f***ing seconds before we were interrupted because every star humper wants a piece of his a**.

‘PS star humper… You are so f***ing rude to me and my 94-year-old father. F*** you star humper.’

Two days later, the 36-year-old took the gloves off and began laying into her younger sister – starting with a smiling selfie of the pair accompanied by a bitter caption.

The blonde wrote: ‘I had to break up with my sister Morgan after her wedding because she’s so concerned with her reputation, she called me ‘insane’ online for the world to hear.’

She added: ‘This has impacted my ability to have children and become a mother and I have to protect myself from further heartache from this image driven monster.’

Next came a flurry of posts that compared Morgan to Disney villain Morgana and a family snap showing Eastwood with Dina and six of his seven children at his Carmel ranch captioned: ‘My siblings are weird and fake, inside and out.’

Next in the social media onslaught came a flurry of posts that compared Morgan to Disney villain Morgana

The blonde wrote: ‘I had to break up with my sister Morgan after her wedding because she’s so concerned with her reputation, she called me ‘insane’ online for the world to hear'

Kathryn then doubled down by posting another photo of herself with Morgan, who is currently pregnant with her first child, and commenting: ‘She’s the cruelest, most shallow superficial woman I have ever known

Kathryn then dubbed the family unity seen at Morgan’s lavish wedding to energy salesman Tanner Koopmans, 27, ‘a performance’ and added ‘my siblings suck’.

Dina, who divorced Eastwood in 2014 before marrying second husband Scott Fisher in 2016, then waded into the row – confronting Kathryn via text and threatening legal action and consignment to a mental health facility over the string of posts.

Undeterred, the 36-year-old, whose mother is flight attendant Jacelyn Reeves, now 72, posted screenshots of the messages to Instagram, adding ‘here’s what my liar of a wicked stepmother has to say’.

In the texts, a furious Dina says: ‘One more comment about Morgan online – and if you don’t erase the ones you’ve posted – I will take legal action against you.

‘Your psychosis is leading you down a very bad legal path and a path that could end up with you being committed to a mental facility.

‘Stop now. I f***ing mean it young lady you stop it right now [sic]. You will lose for family for eternity just like you want but we won’t go down sweetly.’

DailyMail.com can reveal Morgan’s mother Dina, 58, has also been drawn in – threatening Kathryn with legal action over her social media outbursts and being called a ‘greed [sic] money obsessed psycho’ in return. (Pictured: Dina and Clint when they were together in 2010)

A final text exchange, that sees Kathryn reply to Dina with ‘Bring it on. You gold digger’ while her stepmom tells her to take her meds and not be a ‘public attacker’, was posted with a caption accusing Dina of being after Kathryn’s inheritance

Further text messages, accompanied by a caption written by Kathryn that reads ‘my stepmother is a greed [sic] money obsessed psycho and phony reality star’ make more legal threats.

Further text messages, accompanied by a caption written by Kathryn that reads ‘my stepmother is a greed [sic] money obsessed psycho and phony reality star’ make more legal threats.

They also refer to a previous family row over Dina’s divorce settlement, with the 58-year-old writing: ‘I’ll give you until tomorrow morning. Then I will use your father’s money that I stole for him in your words and sue you.’

A final text exchange, that sees Kathryn reply to Dina with ‘Bring it on. You gold digger’ while her stepmom tells her to take her meds and not be a ‘public attacker’, was posted with a caption accusing Dina of being after Kathryn’s inheritance.

It read: ‘My evil stepmother who is after my inheritance and father’s fortune has me committed because she wants money.’

Kathryn then doubled down by posting another photo of herself with Morgan, who is currently pregnant with her first child, and commenting: ‘She’s the cruelest, most shallow superficial woman I have ever known.

‘Zero compassion for others, obsessed with self-image and as cruel inside as she is beautiful without, her looks will fade like a flower and all that will be left is a heartless monster meet my evil stepsister.’

The posts are in stark contrast to the happy family on show at Morgan’s wedding on June 15 and also contrast with previous posts about the 27-year-old.

One June 9 post uses the same smiling photo of the sisters together as the tirade but is captioned with ‘my baby grew up and is having babies’.

A second post made the same day shows the sisters together as children with Kathryn writing: ‘I’m celebrating MY baby, who is all grown up and about to have HER baby!

‘I LOVE MY baby and I couldn’t be more proud of her and her new adventure into motherhood.’

Another post showing the two sisters includes the caption ‘I love my google’ while further photos show Kathryn enjoying the wedding – posing for one photo under the same rust, cream and gold floral arch Morgan was married beneath.

Several of Morgan's half-siblings attended the nuptials, including her sister Kathryn Eastwood who shared a photo booth strip of pictures with their dad (pictured). This was before Kathryn went on to slam Morgan in a series of incendiary social media posts 

Dina, Kathryn and Morgan have all been contacted for comment.

The wedding at Eastwood’s Mission Ranch saw all the Eastwood children brought together, including eldest daughters Laurie Murray, 69, and Kimber, 60.

Kathryn’s brother Scott, 38, was also at the event as was Eastwood’s daughter with Titanic actress Frances Fisher, Francesca, 30.

His final two children, Kyle, 56, and Alison, 52, who he had with first wife Maggie Johnson were also at the wedding.
