Selena Gomez has revealed that bumping into 'Friends' superstar Jennifer Aniston was an embarrassing experience because the chance meeting made her so nervous.

Speaking to Radio Disney recently, the beauty explained that she got really starstruck when they ran into each other and couldn't even bring herself to speak to Aniston although she tried to initiate a conversation:

"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."

In the early hours of this morning (April 9), Gomez told her fans to expect a surprise and tweeted:

"Sorry Everyone, I was in the studio and it went a little long. So my surprise is going to take a little linger and I will have it up ASAP."
