(Cover) - EN Star Style - Selena Gomez won't be wearing boyfriend Justin Bieber's perfume, says a source.

Justin launched fragrance Someday recently, but his 18-year-old girlfriend Selena has reportedly stopped wearing the scent, claiming it was made for his fans.

Justin, 17, has given bottles of his newly-launched perfume to a number of other females in his life, including his hoards of adoring fans and his mother, Pattie.

"Selena has got a bottle but she stopped wearing it when she realised Justin's mother was wearing it too," a source close to the star revealed. "Selena doesn't want to smell like Justin's mom and she feels the scent is more for his fans anyway."

Justin, who has been romancing Selena for several months now, was embroiled in a security mess up last Thursday, when he was tackled to the ground by an undercover officer.

The teenage singing sensation was at New York superstore Macy's to launch his new fragrance Someday, when a man - who was later revealed as an undercover cop - leaped over the metal barrier and tackled him to the ground. (C) Cover Media
