You wouldn't place Gordon Ramsay as a fast food lover, but the chef's become the latest LA-based celebrity to confess to having a guilty pleasure ... he likes his burgers "animal style".

Speaking in Beverly Hills at a special Q&A on the US version of his show Hell's Kitchen, the chef admitted he's a big fan of one legendary Californian burger chain.

"I keep a low profile, but I sneaked into In-N-Out burger the other day. Animal style, that's the secret code, I've got all these code names now for fried onions mixed in with my cheese.

"People think that American's are obese and burgers are bad for you - they are delicious."

Gordon clearly wasn't afraid to pig out: "I was so bad - I went and sat in the restaurant and had a double cheeseburger animal style, and then 15 minutes later drove back around in my car and got the same thing as a take-away. Mmmmm"

He's not the only celebrity that has confessed to loving the chain. Bob Hope was one of the first to admit he enjoyed tucking in to the take-away.

Angelina Jolie admitted that she left the 2003 Academy Awards ceremony early to stop for an In-N-Out on the way home.

But chef Ramsey doesn't need to watch his weight - his current exercise regime is running home after a long shift in the kitchen: "I don't think chefs should be fat, I was a fat chef once and it's not a very good thing to go and say hello to a customer when your stomach is bulging over the table."
