Selena Gomez admits she was starstruck meeting Jennifer Aniston and ''ran away'' from the 'Friends' star because she was ''terrified''.
The 'Spring Breakers' actress was so ''terrified'' when she met the 'Friends' star - who is one of her acting idols - she walked away from her and admits that the awkward encounter is one of the most embarrassing moments of her life.
In an interview with Radio Disney, she explained: ''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.''
The 20-year-old beauty blamed her strange behaviour on watching Jennifer in hit sitcom 'Friends', in which the 44-year-old actress played Rachel Green for 10 years.
She laughed: ''I didn't know what to do - it's Rachel!''
Meanwhile, Selena - who split from 'Baby' singer Justin Bieber last year - has insisted that her new single, 'Come and Get It', is not about her former boyfriend.
She said: ''It's not really about a specific person ... It exudes confidence and strength and that is something I'm willing to share with the world ... I want to represent something good and be a good example.''
The star also revealed to Ryan Seacrest on his radio show that she is planning a huge bash to celebrate her 21st birthday in July.
She added: ''I'm gonna have a big party. It's gonna end up at my house. I wanted to do like a hip-hop theme.''
