Peter Facinelli reportedly appeared "totally smitten" with Jaimie Alexander at a Screen Actors Guild (SAG) Awards after-party.
The Twilight hunk has been dating actress Jaimie for several months and they were happy to show off their fledging romance at the Weinstein Company's bash at Sunset Tower in Hollywood last night.
The pair got to the event at around 9pm and appeared excited to be seen together.
A source told Us Weekly Peter seemed "totally smitten" with his girlfriend, who stunned in a plunging black dress by Marc Bouwer at the ceremony earlier in the day.
As the party continued the pair were spotted dancing to The Notorious B.I.G.'s track Hypnotize together and couldn't help their smooching as they showed off their moves.
The new couple went public with their relationship in November, when Peter was promoting the final Twilight movie Breaking Dawn - Part 2.
"Peter's a classy guy who cares a lot about the people [around him] and... he makes me laugh," Jaimie said at the time.
A number of big-name stars were at the event, including best film actress winner Jennifer Lawrence who was spotted chatting to her Silver Linings Playbook co-star Bradley Cooper.
Julianne Moore, Anne Hathaway, Isla Fisher, Sacha Baron Cohen, Sofía Vergara, Amanda Seyfried, Damian Lewis and Robert De Niro were also there, with Nicole Kidman and Naomi Watts choosing a table together.
Chris Tucker was seen engaging in a dance battle with Glee star Harry Shum Jr., according to E! Online. Harry's co-star Matthew Morrison also got in on the action, with Cuba Gooding Jr. happy to strut his stuff too.
