Taylor Swift is ''disappointed'' in Selena Gomez.

The 'Blank Space' hitmaker is reportedly annoyed with her close friend after the 22-year-old singer was spotted meeting up with her on/off boyfriend, Justin Bieber.

A source shared: ''Taylor is so disappointed that Selena went back to hang out with him, she really has been shaking her head over the whole situation.

''But Taylor doesn't know what to do because she has already done everything to tell Selena that Justin is the worst.''

Justin and Selena were seen enjoying dinner together at Mastro's Steakhouse in Beverly Hills, California on Thursday night (15.01.15), which has reportedly angered the 25-year-old singer, who is ''tired'' of being Selena's shoulder to cry on.

A source added: ''They are still friends but Taylor is looking down on Selena for doing this. She doesn't want to pick up any more of Selena's tears.

''She will, but it's tiring and nothing Taylor wants to do right now.''

Meanwhile, Taylor previously told Selena to ''take a year off dating'' following her split from the 'Baby' hitmaker.

At the time, a source told HollywoodLife.com: ''[Taylor] wants her to at least try taking a year off dating. She thinks she should date herself for a while, take the time to get to know herself and appreciate herself.

''But she's not going to force it, she's trying to lead by example this time, instead of forcing her ideas down Selena's throat, she realises she can be kind of pushy and she's working on that.''
