We thought Justin Bieber had a way with women and that he and pop hotty Rihanna were good friends.
But if RiRi's behaviour at the weekend's Billboard Music Awards is anything to go by, she's not interested in hanging out with the 17-year-old.
The Mirror has reported that Rihanna'sbodyguards stopped the pint sized One Time star from trying to talk to the Rude Boy star, a total of 5 times during the night!
A source revealed: "Justin thinks Rihanna is the most beautiful woman and supremely talented.
"He is in awe of her. Justin is just a red-blooded teenager, he can't help acting like a love-sick puppy dog when he's around her."
The source continued: "The pair were chatting as Justin's girlfriend Selena looked on, scowling. Then Rihanna got dragged away by a couple of her friends."
"The pair resumed their chat later but when Justin went to talk to her at the show's climax her security blocked his path, telling him to 'leave it'."
They added: "Justin looked mortified - he thought they were buddies."
Ouch. Bet that bruised JB's ego!
