Selena Gomez continues to push on and even flourish while her ex-boyfriend Justin Bieber struggles with his image overseas and at home.

The actress, 20, attended the Los Angeles premiere of "Spring Breakers" at the Archlight Hollywood on Thursday. She looked amazing in a red Reem Acra gown with a plunging neckline paired with Giuseppe Zanotti heels.

Gomez is reportedly more than okay with the end of her relationship to the pop star. A source told earlier this week: "Justin is crazy and she doesn't want to be his mom anymore. She feels so free and loves hanging out with her girlfriends."

She hung out with Vanessa Hudgens, Rachel Korine, Ashley Benson, Ashley Tisdale at the film's premiere.

The film centers on four college girls who rob a diner to fund their spring break and wind up hooking up with a drug dealer who bails them out of jail. It opens wide in theaters on March 22.
