The actress, 28, stunned in a super-sexy black Marc Bouwer gown with a plunging neckline, an open back, and curve-flattering ruching. Her beau, who helped open the show with a champagne toast, donned a classic black tux.
The Jan. 27 SAG event is one of the couple's biggest red carpet appearances to date. The Nurse Jackie co-stars first debuted their relationship at a Nov. 15 screening of The Twilight Saga: Breaking Dawn -- Part 2 in New York City, where they held hands and stole covert kisses throughout the night.

The duo worked the red carpet again at a Tommy Hilfiger and GQ "Men of New York" party a couple of weeks later, where Alexander opened up to Us Weekly about her relationship with Jennie Garth's ex. (Garth and Facinelli announced the end of their 11-year marriage in March 2012. They share three daughters, Luca, Lola, and Fiona.)

"Peter's a classy guy who cares a lot about the people [around him] and...he makes me laugh," Alexander gushed to Us of her beau. "That's really more than I've ever found with anyone else."
