Bieber, a pop star who turns 17 on Tuesday, March 1, and Gomez, a fellow singer and the 18-year-old star of the Disney Channel series 'Wizards of Waverly Place', have not confirmed a relationship but have in the past few months been the target of dating rumors.
On the red carpet of the Oscar after-party, Gomez and Bieber looked cozy as they posed for photos. The actress wore a red Dolce and Gabbana gown, while Bieber donned a black suit by the same label.
Earlier this month, they were photographed holding hands in Los Angeles. Gomez has said in the past it would be 'illegal' for her to hook up with the underage singer.
Justin Bieber is so popular that he usually has scores of young girls following him around. Several of his fans sent Gomez threatening Twitter messages last month after she and Bieber were spotted kissing and getting grabby in the Caribbean. In December, they were seen having breakfast at an IHOP restaurant.
Last year, some Bieber fans also attacked reality star Kim Kardashian on Twitter after she and the pop star posed for an Elle magazine photo shoot.
