Bieber & Gomez: Did They Break-up?

Is there trouble in paradise for Justin Bieber and Selena Gomez?

PEOPLE reported that Gomez, 19, “was crying about Justin and was upset” during Ashley Tisdale’s birthday bash last week.

But multiple photos from the fete show the “Love You Like a Love Song” singer all smiles, appearing to be in upbeat spirits. She was even photographed being twirled around by a man identified as Bieber’s close pal Alfredo Flores.

TMZ reported last Monday that the young lovebirds broke up last week, but have since got back together.

The couple faced split rumours last August, but quickly proved they were still an item when they sat next to each other smiling at the Teen Choice Awards.

After publicly confirming their romance by smooching during a press conference in May 2011, their relationship has included over-the-top date nights, a helicopter trip and family bonding.

Just a week ago, Gomez, and Bieber, 18, were photographed wearing coordinating outfits at the Katy Perry: Part of Me 3D premiere.

Neither half of the Twitter-happy pair has addressed the breakup reports.? Reps for the stars have not responded to a request for comment.
