Ali Larter & Hayes MacArthur's Lovey-Dovey Champagne-Filled Date Night

Leaving their little one for the night, Ali Larter and hubby Hayes MacArthur stepped out for date night on the rooftop of Hotel Americano in New York City last week.

Celebrating Perrier-Jouet’s Enchanting Tree launch, the pair sipped on champagne and seemed “so in love,” according to an onlooker.

“Ali kept touching Hayes’s knee,” the source says. “She would stop to talk to people and then would always come back to him.”
