We're the Millers star Emma Roberts has admitted that she was star struck when she first met her co-star Jennifer Aniston.

The 22-year-old niece of actress Julia Roberts explained that she was blown away when she met the Horrible Bosses star and didn't know how to react around her.

Speaking to InStyle magazine about meeting the Friends star for the first time, Emma said: "Surreal. When I met her she came up and gave me a big hug. I was so star struck I froze with my arms by my side and just said 'Hi, I'm so nervous to meet you.'"

It's not the first time she's been star struck - she's also in awe of Johnny Depp after working with him on 2001's American biopic Blow.

"At the time I didn't really know who he was, but now . . . Oh my God. I have a black and white picture hanging in my house that he signed for me saying, 'To Emma, one of the most beautiful people I've ever met.' My friends come over and they're like, 'Is this for real?'"
