NEW PHOTO: Simon Cowell & Ryan Seacrest Leave London Stripclub

They may appear like sniping enemies on American Idol, but Simon Cowell and Ryan Seacrest enjoyed a 'guy's night out' together at London's famous Stringfellows stripclub Thursday night.

A lipstick smeared Cowell and a smirking Seacrest were snapped leaving the club after sampling some of its delights from 10 pm to 3.30am.

The two seemed to have a blast in the popular strip club where lap dances are available for around a $100 a shot.

Ditching his trademark black t-shirt, Cowell made an attempt to impress the ladies by wearing a smart navy blue suit while Secreast dressed 'smart but casual' for their rowdy night out.

The radio host is on a short visit to London and seemed very keen to allow his Idol nemesis to show him around the British capital.

Multi-millionaire Cowell is a close friend of Peter Stringfellow who founded the famous strip club chain and he was occasional visitor in the past.

He was pictured with one hot blonde back inside the club in 2003 but once he started dating Terri Seymour the following year the visits stopped.

Their strip-club adventure comes as a departure for the pair as Cowell usually prefers more sober establishments like Mayfair restaurant Scott's or the Dochester Hotel's China Tang while Seacrest frequents low-key restaurants and bars in Los Angeles. (Photo: Rex USA)
