London, July 8 (ANI): Rap star 50 Cent had to seek "pop Queen" Madonna's help to bring his pal Justin Timberlake out of the dressing room, while the singer was getting ready for a video shoot in London studio on Friday.

Sources have revealed that the rapper was so fed up waiting for Timberlake to be ready that he had to rope in Madonna, who was rehearsing for Live Earth concert in a studio nearby, to get his pal out of his dressing room.

They also say that the 'queen of pop' was giggling like a schoolgirl as she helped 50 Cent get the 'Sexyback' singer out of his room.

"They both started bashing on his dressing room door. Madonna shouted, 'Come on, Justin, you're holding up the shoot'. She was giggling like a schoolgirl," the Sun quoted a source, as saying.

The 'Ray of Light' star's intervention worked and the two got down to business quickly. (ANI)
