Renée Zellweger is set to appear in the second season of her boyfriend Ant Anstead's reality show, Born Mechanic.

The actress, 56, best known for her portrayal of the unlucky-in-love Bridget Jones, appears in the first episode of the new series to surprise toyboy Ant, 46. 

Back in February, rumours began swirling stating the couple were on the rocks however representatives squashed the claims - with her appearance on the show further cementing their union.

Renée is set to gift her boyfriend a 'cool addition' for the farmhouse he is renovating for his parents on the show - funding the project by restoring old cars. 

The show's synopsis reads: 'Master mechanic Ant Anstead is back restoring and selling old cars from his ramshackle barn. 

'Any profit goes to renovating the farmhouse he's bought for his parents. But with major structural issues, moving them in before summer's out is a big challenge.' 

The first episode is otherwise centred on Ant's decision to gamble on the purchase of a Mark1 Capri which he suspects has a 'hidden secret'.

Despite being advertised as a GXL, the car expert suspects that it could, in fact, be a more valuable GT. 

News of the show comes after Ant's representatives addressed rumours that she had split from Renée after it emerged that they were living apart earlier this year. 

The couple, who began dating in 2021, have not been seen together in public since early March when they were snapped supporting his young son at a soccer game.

Earlier this year sources told Daily Mail the couple have been living apart, but a rep for the TV host added the couple 'are still together.'

The couple are otherwise very private about their relationship, but Renee provided rare insight into their romance in an interview with British Vogue back in January.

Speaking about Ant and his son Hudson, five, in the interview, she said: 'I live in Southern California, near San Diego, because that's where my fellow lives, and his little boy'.

Ant shares Hudson with his ex-wife Christina Haack. He also shares daughter Amelie, 21, and son Archie, 18, with his ex-wife Louise Anstead. 

In February, friends of the actress told Daily Mail that she had put the brakes on her relationship with Ant, revealing she is not interested in marriage.

'Renée and Ant have been dating for over three years,' one insider said. 'She loves the relationship the way it is.

'She's seen so many couples, especially celebrities like Brad Pitt and Angelina Jolie who have happily dated, only to split not long after getting married.

'Why would she risk rocking the boat and rushing to take her relationship with Ant to the next level?' 

Cars have been Ant's focus since he left his prior career as a policeman in 2005 to restore them. 

He went on to find fame on Channel 4's For The Love of Cars and has also presented Wheeler Dealers. 

Born Mechanic is set to air weekly on Quest from September 16.
