Selena Gomez and Justin Bieber have reportedly split up after nearly two years of dating.
A source close to the couple told ABC News that the couple broke up about a week ago, noting that their busy schedules made it hard to maintain a relationship. Gomez and Bieber and their respective reps had no immediate comments on the rumors.
Rumors of a split began earlier in the month and became fan fodder after 18-year-old Bieber was seen spending time with Victoria's Secret model Barbara Palvin, 19. The pair were seen with friends attending "The Lion King" on Broadway and also appeared in two photos together, which were posted online.
Palvin shared a photo of her and Bieber backstage at the Victoria's Secret Fashion Show, where the pop star performed on November 7. Palvin also appeared in the background of a photo posted on rapper Lil Twist's Twitter page, which Gomez re-Tweeted, with the caption, "......"
Palvin denied she was dating Bieber, Tweeting on November 9, "hey everyone. please calm down. he is all yours!! :) please."
Gomez, 20, and Bieber first sparked dating rumors in December 2010, when they were photographed at an IHOP in Philadelphia. The following month, in January 2011, the two were photographed kissing and getting grabby in St. Lucia, where they rang in the New Year. After the pictures surfaced online, Gomez received death threats.
In February 2011, the two sparked rumors of an engagement when Gomez was spotted wearing a diamond ring on her engagement finger. Her spokesperson denied the female singer had plans to wed.
Bieber is currently on a world tour to promote his recent album, "Believe," while Gomez recently warapped production on the Disney Channel's "Wizards of Waverly Place" TV movie, which she executive produced.
