Renee Zellweger and Ant Anstead looked happy in love as they prepared to celebrate a friend's birthday at a winery in Temecula, California on Friday. 

The 52-year-old Bridget Jones's Diary star appeared joyful as she warmly embraced a few of her pals before hopping on a party bus for a fun time. 

After getting out of the driver's seat, the Wheeler Dealer host, 42, came around the car to stick by his girlfriend's side as they mingled with their buddies.

For the excursion, the two-time Oscar winner wore a black puffer vest, grey pants and an orange UT Austin baseball cap from her college alma mater. 

Her beau looked handsome in a tight black t-shirt, which showed off his  muscular physique, and a pair of light-wash jeans. 

The father-of-three completed his laid-back look with a pair of red star-shaped sunglasses sunglasses hanging from his shirt's neck.  

He and Zellweger, who carried a small box with a massive red bow, both wore colorful birthday caps to the party. 

The duo engaged in some light PDA as the Judy actress tenderly placed one hand on his chest and he walked with a hand on her shoulder. 

Zellweger seemed amused by her paper crown, which she wore over her cap, as she pointed toward the top of her head in one lively conversation. 

The lovebirds have been dating since June 2021 after meeting on the set of Ant's Discovery+ show, Celebrity IOU: Joyride.

In November, the Bridget Jones actress rented a five-bedroom Laguna Beach mansion for $30,000 a month, across the street from Ant's home, which he announced would be undergoing an extensive remodel. 

Ant shares daughter Amelia, 18, and son Archie, 15, with his ex-wife Louise Anstead. He is also father to Hudson, two, whom he shares with ex-wife Christina Haack, 38. 

Renee, who was briefly married to country singer Kenny Chesney, 53, celebrated Thanksgiving with Ant and Hudson.

A source recently told Us Weekly, 'Ant and Renée are going strong.'

'Their relationship is progressing naturally. They've just been happy together and look forward to growing as a couple.'

The source added, '[They] can't wait to see what the new year has in store for the both of them.'
