The 38-year-old brought his new girlfriend Jaimie Alexander to the SAG Awards last night and according to US Weekly, the two were "totally smitten."
The pair were spotted at the Weinstein Company's after party and hit up the dance floor showing off their moves to B.I.G.'s "Hypnotize."
They were also seen getting hot and heavy kissing outside on the patio while snuggling up to stay warm by the heat lamps.
Peter made his first public appearance with Jaimie at a NYC screening of The Twilight Saga: Breaking Dawn — Part 2 last night on November 15.
The two met on the set of Nurse Jackie where she costarred in a few episodes of the show with Peter. She was also in the film Loosies, which her new man wrote the screenplay for.
