It seems like Selena Gomez has made up her mind to be with Zedd, as her dinner date with ex-boyfriend Justin Bieber apparently left her in disappointment.

TMZ recently reported that Gomez and Bieber were spotted grabbing dinner together at Mastro's Steakhouse in Beverly Hills on Jan. 15.

According to HollywoodLife.com, 'The Heart Wants What It Wants" singer was rather upset about the recent meet-up, because the "Boyfriend" crooner did not even try to rekindle their relationship.

"It was a huge disappointment for Selena because he's basically the same Justin... all talk and basically about himself," a source revealed. "He was bragging about himself the whole time, and how 2015 was going to be his best and most successful year ever. Selena thought he was going to try and win her back and profess his undying love, but he didn't."

"He knew she was staying at Sunset Towers and left a bunch of messages for her so she said she would meet him to talk. But it was bittersweet, that's it. It's like she ripped open an old wound, when she should have just left it alone," the source continued.

An eyewitness similarly claimed that there was nothing romantic about the ex-couple's reunion:

"It seemed like Justin was doing most of the talking. It didn't look like they were on a date -- there was no kissing, hand holding, or anything lovey dovey -- just a lot of talking and nodding. They weren't here for very long, maybe an hour or less."

With that being said, Gomez might be moving on from Bieber for good by dating the EDM star. She took to her Instagram account on early Monday morning to share a snapshot of herself with her rumored new beau, captioning that she misses him:

Another source claimed that Selana Gomez is happy about her new romance with Zedd: "Selena is on cloud nine. She's never been happier and definitely has Zedd to thank for that. She's absolutely smitten with him."

"First off, Selena feels like he totally gets her on so many levels. They never run out of things to talk about it. One night they stayed on the phone for four straight hours talking. It's crazy," the source added.
