It’s been more than a year since Hugh Grant and then-girlfriend Jemima Khan parted ways after three years together. So it’s about time the hunky Brit found himself with a new lady love. And judging by how things went this weekend in the Hamptons, he might have found just that.

At the Taste of Evian polo party on Sunday, the actor, who celebrates his 48th birthday on Sept. 9, seemed to make no attempt to hide his affection for 27-year-old fashion designer Catherine Fulmer.

"They were so cute and flirty," a fellow partygoer tells OK!. "He got Catherine and several of her friends shots of Milagro tequila to celebrate the night."

However, a rep for the actor tells OK! that this is all much ado about nothing: "Someone’s got their wires crossed. They met at a party and Hugh does not know her at all."
