It’s a reality TV overload! X Factor stars John and Edward Grimes bumped into American Idol star Adam Lambert at a party in London last night.

Adam is currently touring Europe promoting his debut album ‘For Your Entertainment’, while the Jedward’s where in the city to record their jingle for the new Shake and Vac advertisiment.

The Grimes twins posted the pictures of them partying with Adam on their Twitter page today and sent the star a message saying:

MAN YOU ROCK THANKS FOR THE PICS SO COOL PEACE OUT JOHN AND EDWARD

The crazed pair also met The Black Eyed Peas who played London’s O2 arena last night, check out the picture below.

We wonder what all the Americans thought about being caught up in the whirlwind of the energetic Irish boys…… It can’t be easy!
