Justin Bieber has banned One Direction's Harry Styles from going anywhere near his "really hot" mother.

Harry, 18, is famed for romancing older women and has had flings with a couple of more mature ladies. One Direction have become friendly with Justin of late, and although the Canadian superstar loves hanging out with the British group, his girlfriend Selena Gomez insists he's wary about Harry being around his mom.

"Justin has become really good buddies with the guys, and we know some beautiful young women in the industry who have major crushes on Harry. He could probably pretty much take his pick from the hottest young girls in Hollywood. But from what Justin has been telling me, it's not the young girls he's looking at!" she exclaimed to British newspaper The Mirror.

"I guess you just can't blame him when you see how hot women such as Cameron Diaz, Eva Longoria, and Sofia Vergara look. Both me and Justin still have really hot moms, and Justin was like, Harry might have become one of my best buddies, but with his record we need to keep him away from our moms.'"

Meanwhile, a crafty One Direction fan outsmarted security in order to meet the band, which also comprises of Louis Tomlinson, Niall Horan, Zayn Malik and Liam Payne.

When a lookalike of Louis' girlfriend Eleanor Calder sparked a frenzy outside a show in Houston, Texas, the band's security team let her through.

"Fans outside the gig believed this girl was Eleanor and started hounding her about Louis and asking for her autograph. Security saw the commotion and took her inside the venue to present to Louis, who obviously told them it wasn't her," a source told British newspaper The Sun.
