It's the dawn of a new relationship for " Breaking Dawn - Part 2" star Peter Facinelli. The 38-year-old " Twilight" actor and estranged husband of Jennie Garth was spotted last week with "Thor" actress Jaimie Alexander, 28. The two dined at the East Village pub The Penny Farthing before walking the red carpet for the NYC premiere of the last "Twilight" movie.

The two got to know each other while filming "Loosies," a movie about a pickpocket (Facinelli) who comes face to face with a former one night stand (Alexander) that came out in January. Garth filed for divorce from Facinelli in March.

Meanwhile, the 40-year-old "Beverly Hills, 90210? actress is trying to sort out her holiday plans. This will be the first Thanksgiving she spends without her three daughters, Luca, Lola, and Fiona. "This is my first shared holiday," Garth told Us Weekly last week. "Their dad and I are hammering out the details of that, which is weird. They're actually gonna be with him for Thanksgiving and I'm gonna be with some friends, and then I get to have them for Christmas."

"We're gonna do our Thanksgiving on Saturday," she added. "I'm going to make a whole meal, have them go shopping with me and help me bake everything, and my mom and her husband are gonna come over."
