What's in a name? Everyone's got one, some are common, like Bob Smith or Bill Jones, and others are exotic, original or just plain different.

Olivia Wilde, above, has a unique name. Olivia isn't the most common of names, and Wilde isn't exactly original, but put them together and take one look at the actress and one can only think that she's a bit adventurous and intriguing.

Wilde, however is just her stage name, but a well-chosen one at that. Olivia's real last name is Cockburn. She was born Olivia Jane Cockburn, which is pretty awesome itself.

Unfortunately she's not that adventurous though: she appeared to go topless in 2011 film "The Change-Up", but instead she wore pasties for her nude scenes and the special effects team added her nipples digitally.
