Katy Perry has confirmed her boobs are real but says she would refuse to strip off for a Playboy shoot.

Our sister site 3am.co.uk can’t stop going on about the singer’s fantastic chest and bizarrely Katy believes there are people who think she has had a little help up front.

In an interview with YouTube Katy said: “My boobs are real, just wanted to cover all that.”

When asked if she would pose for Playboy Katy says: “I would probably say no, because I think…that’s showing all your cards. And, like, I always want to keep a couple aces up my sleeve. And plus I think it’s a fine line to tease and then to just give it away, and I like to be considered more of the tease.”

In the interview, which you can watch here, Katy also reveals that actress Natalie Portman is next on her kiss list because she’s “H๏τ and smart”.

She explained: “I used to want to kiss Megan Fox but now she’s married and I’m not so sure about that anymore.”
