Justin Bieber has admitted he’s not in the “happiest place” after his break-up from Selena Gomez, but the Wizards of Waverly Place star seems to be in good spirits.

Gomez attended a Nylon magazine party in West Hollywood on Tuesday night, celebrating her cover. She also celebrated with a private dinner at Soho House with family and friends.

“She was so happy,” a source said, Us Weekly reports. “It was a total girls night, and she was hanging out with her parents and close friends.”

The friends she was hanging out with include Ashley Tisdale and Jaime King as well as her Spring Breakers co-star Ashley Benson.

Meanwhile, Gomez’s ex released his album Believe Acoustic on Tuesday, where he debuted a song called “Nothing Like Us,” an emotional ballad about their break-up.

Gomez told E!’s Marc Malkin "I've been telling people I'm definitely a little bit more sassy now," adding, "I'm a little bit more mouthy."

She also said about recording her new album "I'm having a lot of fun expressing everything that I'm feeling."
