London, May 7 (IANS): Singer Justin Bieber was surprised when one of his friends asked him for Rihanna's phone number.
"The lads are really cool. We stay in touch. You can't tell your bro's secrets, but one of them did text me asking if I could introduce them to Rihanna," dailystar.co.uk quoted the 18-year-old as saying.
"I can't say which one. He is a great guy, so if Rihanna wants herself a younger man he could be in with a shot," he added.
