Gigi Hadid and Bradley Cooper have finally gone Instagram official.

The supermodel shared a series of photos from her 30th birthday party on Instagram Saturday, and among them was a photo of Hadid kissing Cooper.

In the steamy picture, Hadid and the 50-year-old actor could be seen passionately kissing while standing behind her giant, three-tier chocolate birthday cake.

Hadid cupped Cooper’s face in her hands as they enjoyed the smooch.

“I feel so lucky to be 30!” she captioned her carousel of photos.

“I feel so lucky for every high and low – for all the lessons and gifts both have brought me. To get to feel it all! I’m so lucky to be a mom, friend, partner, sister, daughter, colleague to some of the most unbelievable humans!!”

“So lucky for the support and encouragement from all of YOU around the world, every day and on my birthday last week,” she continued.

“I had the best time celebrating, and it’s a blessing to feel so loved!! I am grateful and honored to take on a new decade.”

Hadid’s post comes one week after she and Cooper were pictured arriving at the April 25 party.

The happy couple was seen holding hands as they entered Le Chalet in New York City. Notably, Hadid had a shiny new accessory on her wedding ring finger — a gold ring.

Hadid and the “A Star Is Born” actor were first romantically linked in October 2023, when they were spotted on a dinner date at Via Carota in New York City’s West Village. Since then, they’ve only gotten closer.

As recently as March, the “Next in Fashion” co-host gushed over her partner in an interview with Vogue.

“Getting to the point where knowing what you want and deserve in a relationship is essential,” she said. “And then to find someone that is in a place in their life where they know what they want and deserve. And you both do work separately to come together and be the best partner that you can be.”

“He gives so much to me: encouragement and, just, belief. For those people you admire to encourage you, it can create so much belief in yourself. Like, what’s the worst thing if I auditioned for this?” she continued.

Cooper is dad to 7-year-old daughter Lea, whom he shares with ex-girlfriend Irina Shayk.

Gigi, meanwhile, shares 4-year-old daughter Khai with her ex Zayn Malik. She and the former One Direction member, 32, broke up in 2021 after more than two years of dating.
