WILL ARNETT DEBUTS ROMANCE WITH GIGI HADID'S BFF LEAH MCCARTHY AT STAR-STUDDED BIRTHDAY BASH

Looks like Gigi Hadid's 30th birthday celebration wasn't just about honoring the supermodel – it might have also served as a coming-out party for a new celebrity couple! Actor Will Arnett was spotted arriving at L'Avenue at Saks Fifth Avenue with Gigi's close friend, Leah McCarthy, sparking immediate buzz about a blossoming romance.

While the paparazzi flashbulbs captured their arrival, several sources have since reached out to Deuxmoi with whispers of a connection brewing between Arnett, 54, and McCarthy, reportedly 30. One insider claims to have witnessed the pair looking very cozy during a brunch outing in Sag Harbor a month ago, noting McCarthy was "all over him" – though the onlooker didn't realize her identity at the time.

Adding more fuel to the fire, another source reported seeing Will and Leah canoodling for hours at the I Sodi bar just two weeks ago, stating they "definitely seemed like a couple." Further solidifying the timeline, a separate tipster revealed that Leah and Will were spotted on a double date with Gigi Hadid and her beau, Bradley Cooper, at the charming Cafe Cluny back on April 8th.

While neither Will Arnett nor Leah McCarthy have publicly commented on their relationship status, these multiple sightings, culminating in their joint appearance at Gigi Hadid's milestone birthday, certainly suggest that something romantic is brewing between the actor and the model's best friend.
