Renee's Bridget Jones is pictured for the first time with One Day's Leo as her hunky young lover! See our exclusive photos of the pair together on the set of the new movie

The ever-hapless Bridget Jones finds herself stuck up a tree in the next instalment of the hit movie series – but luckily a vv hunky young park attendant is on hand to come to her rescue.

These exclusive pictures show One Day heartthrob Leo Woodall in character as Rockstar, the toyboy love interest of Renee Zellweger's alter-ego, for the first time, as he helps her out of her predicament. But not without sneaking a peek at her bottom as he does so.

Ms Zellweger's character finds herself out on a limb after scaling the tree in search of a stranded child during a family trip to Hampstead Heath in North London.

Leo Woodall, one of the stars of hit series One Day, is dressed in a green t-shirt and matching trousers - the uniform of park attendants on Hampstead Heath 

Woodall, 27, donned the branded green T-shirt and matching trousers of a park attendant for the scenes, recorded on Thursday. He was also seen filming a conversation with the child actor playing Bridget's young son Billy in the film, titled Mad About The Boy.

The scene is reminiscent of the moment in the first movie, 2001's Bridget Jones's Diary, when the TV journalist character slides down a fire station pole.

Ms Zellweger and Woodall were seen filming last Thursday, for the upcoming movie Mad About the Boy

One onlooker on Hampstead Heath said: 'Leo and Renee looked like they were having a great time. There were lots of giggles, they seemed to get on really well'

The fictional love-interest was also seen talking to Bridget's two children after rescuing their mother from the tree

In the new film, Bridget enjoys a fling with Rockstar and PE teacher Mr Walker, as played by 12 Years A Slave actor Chiwetel Ejiofor as well as reviving her on-off relationship with Hugh Grant's Daniel Cleaver and Colin Firth's Mark Darcy. 

Mr Ejiofor, 46, was also seen shooting scenes on the same day last week which means only Mr Grant and Colin Firth – who has a small role in the movie as the late Mark Darcy – are yet to be spotted in character.

The actor shot to fame for his leading role in Netflix's One Day, but he also appeared in The White Lotus

Ms Zellweger, 55, has been busy since she arrived in London two weeks ago to reprise her role as the singleton for the fourth, and probably final, time.

Bridget Jones is renowned for being clumsy and rather ungraceful at times, and it seems nothing has changed

She spent four days filming at ITV's studios in White City, West London, where programmes such as This Morning and Loose Women are made. There she met presenters from both shows, including Cat Deeley who was said to have been 'super excited' at seeing Ms Zellweger. Many studio staff were 'overcome with excitement' and desperate to get selfies with the Hollywood star when they realised that the movie was being filmed at their workplace.

Scenes were recorded on the set used by Ant McPartlin and Declan Donnelly for their now defunct show Saturday Night Takeaway, while audience members from Loose Women were also asked to stay for filming of some scenes

It is the fourth time Ms Zellweger is returning to screens as the beloved singleton Bridget Jones, based on Helen Fielding's books

 Ejiofor, who plays PE teacher Mr Walker, was also shooting scenes on the same day

The tree scene is reminiscent of the moment in the first movie, 2001's Bridget Jones's Diary, when Bridget slides down a fire station pole during a stint as a TV journalist

One source at ITV said: 'It was chaos, imagine having Bridget come to your work. It was literally a dream come true. The place was absolutely buzzing. Word got round so fast, Cat was so excited.'

Bridget's creator Helen Fielding has also been spotted at the filming as she prepares to say goodbye to the much-loved character. The film is due out on Valentine's Day next year.

It was revealed last month that Bridget's obsession with losing weight will be 'played down' in the film amid fears they might be a bad influence.
