Boyband JLS have shown that even they get star-struck at times after recounting a particularly awkward anecdote involving Justin Timberlake and a urinal. 

Speaking to Top Of The Pops magazine, Marvin explained that a chance encounter found him in a compromising situation next to the 'SexyBack' singer:

"Once I was in the toilet and Justin Timberlake walked in. I looked to my left and was like, 'What's up Justin?!'"

Bandmate Aston jokingly added:

"Listen everyone needs to pee. You need to pee, I need to pee, Justin Timberlake needs to pee!"

JLS are currently in Los Angeles working on their forthcoming album, which on April 12 they explained they had "done about 40 songs" for, but despite their stateside location are unable to attend music festival Coachella due to recording commitments and Marvin tweeted:

"Am gutted can't make it to Coachella..I know it's gonna be crazy! Locked in LA studios!"
