Inside Macaulay Culkin and fiancée Brenda Song's Hollywood love story - as pair make a rare public appearance together at a bash in LA

Macaulay Culkin, 43, and his fiancée Brenda Song, 35, have become one of the most loveable couples in Hollywood. 

The pair - who were recently seen in a rare appearance at a Clarins party over the weekend - have been going strong since 2017.

The couple, who both began their careers at a young age, first met on the set of Dads.

She starred on the show with Seth Green and Giovanni Ribisi during its one and only season from 2013-2014, and Culkin had apparently visited his friend Ribisi on set.

Culkin claimed Song at first brushed him off, which she protested when they both appeared on the actor's Bunny Ears podcast. 

They met again when each was cast in Green's comedy-drama Changeland, shot in Thailand in 2017,  and that' when they really got to know each other.

The pair don't speak often about their relationship, but the Righteous Gemstones actor offered a peak into their situation during an appearance on the Joe Rogan Experience in 2018.

'I have a good life now. I've got a special lady friend. We have a dog and a cat. It's one thing to exchange keys. It's another to get a cat,' he explained of their commitment. 

Both Culkin and Song began their careers at an early age. 

After parts in 1988's Rocket Gibraltar and 1989's Uncle Buck, he was cast in 1990's Home Alone.

The movie about a young boy who must defend his family home against some bungling burglars after he's left behind by his parents in the scramble to catch a flight for a Christmas vacation was an instant hit.

Culkin became an international star at the age of 10.

The film made $476.7 million. He returned to the character of Kevin again in 1992's Home Alone 2: Lost in New York, which was nearly as successful as the original, earning $359 million worldwide.

The young actor showed his dramatic skills in the 1991 dramady My Girl, with Anna Chlumsky and Dan Akroyd.

The couple first met in 2013, when Culkin made a guest appearance on the sitcom Dads, in which Song starred. They met and fell in love after both were cast in Changeland, written, directed and starring Dads star Seth Green 

The actress shared a group photo that included Culkin and other cast and crew members from Changeland in 2017 writing Epic first #summerslam ! Shout out to @sethgreen ( aka the king of group selfies ) for this amazing night and epic selfie. Haha'

In a group photo from the Changeland Premiere in 2019, the private pair did not pose together. 'Two years ago almost to the day, I went to Thailand and made @changelandmovie with my best friends. It’s out today in theaters and VOD!! Please check it out!' she wrote

Song began modeling at the age of six and started acting the next year with an appearance the short-lived series Thunder Alley.

After years of appearing in guest spots on various shows, she was cast as a regular in Disney's Phil of the Future.   That show was cancelled after one season, but she got her own starring role in Disney's Wendy Wu: Homecoming Warrior as a California teen who learns she's a reincarnated female warrior destined to save the world.

The couple didn't hit it off after their initial 2013 meeting on the set of Dad. When the actress appeared on her then-boyfriend's Bunny Ears podcast, Culkin said his future love 'totally brushed me off, completely.'

'You're the only person happier for me today than I am. You're not only the best woman I've ever know, you're the best person I've ever known,' he said in a faltering voice as Song wiped away tears from her eyes. 'You've given me all my purpose. You've given me family. I love you. I love you so much.'
