Jennifer Aniston's Oops Moment!

The actress looked stunning in a pretty dress at the glitzy bash but almost put on a bit too much of a show

We love Jennifer Aniston for many reasons - she starred in Friends for many years which was one of our favourite shows EVER, she's funny, pretty and is in loads of our favourite movies.

So we were pleased to see she was in tip top shape at the premiere of her new comedy We're The Millers in London on Wednesday night where she posed up a storm as she arrived at the glamorous event.

Jennifer, who attended the event with co-star Jason Sudeikis, who plays character David Clark, arrived to deafening screams from fans who were waiting to get an autograph and a picture with the actress and the excellent Jen was more than happy to meet as many people as possible.

This all sounds like pretty standard business for a movie premiere but it got even better when Jen, who was flashing the massive engagement ring she was given by fiancé Justin Theroux, almost suffered a wardrobe malfunction and showed her private parts as she leaned in to pose with fans.

However, the star didn't seem to mind and laughed it off by pulling a funny face as she headed further down towards the entrance of the cinema.

When asked how she felt before going into the premiere, she said: "So good, so happy to be here. [The fans are] the most incredible group of people."
