Selena Gomez was mesmerised by Bradley Cooper's beauty.

The 'Come and Get It' hitmaker - who recently admitted to being starstruck by the 'Silver Linings Playbook' actor - worries he may have taken a ''restraining order'' out against her after she couldn't contain her excitement when they met.

She said: ''I just remember seeing him and freaking out and running away very quickly afterward. That seems to be the thing I do. It was surreal. He was so beautiful. I told him I was a big fan. I'll have a restraining order soon.''

The 21-year-old beauty - who is in an on/off relationship with Justin Bieber - is often skittish around her idols and previously revealed she ''ran away'' from 'Friends' star Jennifer Aniston because she was so awestruck meeting the actress.

She said: ''I ran away from Jennifer Aniston when she said, 'Hi.' I was terrified of her. I was scared, so I ran away and I'm really embarrassed about that. I didn't know what to do - it's Rachel!''

The actress-and-singer is set to launch her 'Stars Dance' tour in support of her first solo album and was equally awestruck after seeing Beyonce live on tour, but felt inspired by the 'Love on Top' singer's stage presence.

She explained to 'Extra': ''I could never touch that status, it was ridiculous, but it did give me motivation! That's something that I definitely, at her age, would love to be doing. She's fierce and was definitely owning it that night.''
