Bieber at Gomez's birthday bash
Justin Bieber helped ex-girlfriend Selena Gomez to celebrate her 21st birthday at her party over the weekend.
The Never Say Never singer turned up at Selena's birthday bash in Malibu, California in his boldly patterned leopard-print sports car, said The Sun.
He stayed at the party until 2am and left with the birthday girl, but the pair gave the "Bieber mobile" a wide berth and he escorted her home in a chauffered car instead.
Selena recently insisted there was nothing going on between her and ex Justin.
Asked if blogs and gossip sites play up their relationship, Selena said: "I think they do kind of blow it up in a way and I do think they want to have something to talk about, so that's the easy thing to do... I've known him for a really long time and we enjoy each other's company every now and then.
"But I'm definitely single and enjoying being that."
Justin's behaviour has landed him in trouble in recent months after he urinated in a bucket in a New York restaurant and then sprayed a wall photo of former US president Bill Clinton with cleaning fluid while cursing him.
The 19-year-old singer later contacted Clinton's office to apologise and offered to help out the Clinton Foundation.
