Less than a week after PEOPLE confirmed that Justin Bieber, 18, and Selena Gomez, 20, called it quits, the pair reunited in Los Angeles.
On Wednesday, Bieber met Gomez at LAX airport where a source says he picked her up and drove her home.
According to TMZ, which has photos of the pair separately entering the Four Seasons hotel the following morning, Bieber stayed the night at Gomez's house.
Meanwhile, a source close to Gomez tells PEOPLE "of course" Bieber is trying to win his ex back.
Of the initial split, the insider says Gomez "was heartbroken. It wasn't easy." But, the pal says the former Disney star – who was all smiles at the Glamour Women of the Year event in New York earlier this week – is "being a trouper."
A rep for Bieber would not comment on his personal life.
