Selena Gomez may have attended ex-boyfriend Justin Bieber's concert just a month ago, but she didn't want to meet him and his date Hailey Baldwin at the Met Gala 2016's after party. The "Same Old Love" singer even changed her plans when she found out that her ex would be at The Boom Boom Room, according to a source.

Selena, who attended the Met Gala with best friend Taylor Swift, instead went to Vogue Magazine's after-party with friends. The "Good For You" singer posed for several pictures in the photo booth in the same Louis Vuitton dress that she wore earlier on the Met Gala's red carpet.

"She didn't want to be there with Justin and Hailey. It's a small place and that would just be way too uncomfortable," the source told Hollywood Life.

Interestingly, Justin didn't turn up at The Boom Boom Room either. The "Sorry" singer and Hailey Baldwin were seen at New York City's Up & Down nightclub, where several stars including Bella Hadid, Rita Ora, Taylor Swift and others were present, according to the Daily Mail.

Selena seems to have moved on from their split in 2014. The ex-couple are never seen in public together and rarely talk about the other person. In an interview with Rolling Stones in January, Selena, 23, said, "... honestly, what I would love to be printed is that I am so beyond done with talking about that, and him [Justin]."

Justin and Selena started dating in December 2010 and called it quits four year later, in 2014, after rumours of infidelity rocked their relationship.
