Zooey Deschanel and Katy Perry

 American actress Zooey Deschanel is sick of being mistaken for Katy Perry but it's easy to see why it happens. 'It's a little bit annoying, to be totally blunt. The only similarity that we have is that we look a little bit alike.' More than a little, we would suggest. Keep clicking for more music stars who look like other celebrities...

Erika Christensen

 Erika Christensen has appeared in films like Traffic, Swimfan, How to Rob a Bank and The Perfect Score. For all her acting pedigree, we can't help thinking she looks a lot like a certain teen pop star...

Miley Cyrus

 Come on, she's the spitting image of Miley Cyrus!

Will Ferrell

 OK, here's another. Which drummer does Hollywood funnyman Will Ferrell closely resemble?

Chad Smith (Red Hot Chili Peppers)

 That'll be Chad Smith from Red Hot Chili Peppers. In his own words: 'People come up to me in airports and they're asking for my autograph not because I'm the drummer for the Chili Peppers. They really think I'm Will Ferrell. And I'm nice to these people. I say, 'No, I'm not.' But they're like, 'I loved you in Old School. You're so funny.''

Nicole Scherzinger

 We make no secret of our love for Nicole Scherzinger round these parts but she does look pretty similar to a certain 'entrepreneur, actress, model, socialite'...

Kim Kardashian

 We wonder if Nicole and Kim have ever met. Probably.

Billie Joe Armstrong (Green Day)

 We had to do a double take too!

Michael Cera

 Michael Cera is the loveable geek star of Juno and Scott Pilgrim vs. the World but which self-proclaimed music 'loser' does he closely resemble?

Beck

 Amazingly, there's 18 years between Michael and Beck.

Tom Hardy

 Tom Hardy is currently sporting a shaved head for his role as Bane in the new Batman movie, The Dark Knight Rises. But is he too sexy for his shirt?

Fred Fairbrass (Right Said Fred)
