Selena Gomez enjoyed a girls' night out with her friends Ashley Benson and Ashley Tisdale, who are reportedly helping her get over Justin Bieber.The 20-year-old singer and actress - who split from the 18-year-old Canadian popstar earlier this month after two years together - enjoyed a girls' night out with some of her celebrity pals to celebrate her being the cover star of the February issue of NYLON magazine.The 'Who Says' singer was reportedly the centre of attention as she partied in a sexy Versace Atelier mini dress with Ashley Tisdale, Ashley Benson and Jaime King at the bash in the Soho House in Los Angeles on Tuesday (29.01.13).She told E! News: "I'm good. I'm really good. I've been recording, having a lot of fun with my girlfriends, having a good time."Other guests included 'Glee' actor Chord Overstreet, 'Mad Men' star Kiernan Shipka and 'The Secret Life of an American Teenager' actress Francia Raisa.The 'Spring Breakers' actress was recently said to be doing well and has already moved on after telling friends that Justin was too needy for her.A source said: "Justin is super needy and can be a big baby around Selena. It's hard for him to make real friends because he likes the temporary attention of strangers, but didn't see how it hurt Selena."Selena didn't feel Justin was respectful of their relationship. She was constantly catching him in positions with other girls that would make her uncomfortable. She would get super jealous."The couple broke up shortly after holidaying in Mexico where they had planned to ring in the New Year together but got into a huge argument on December 30 after she allegedly found text messages from other girls on his phone.However, Justin recently admitted he is still devastated about the break-up, saying: "I'm not in the happiest place that I've ever been."
