He's just a teenager in love.
Although the volatile pair had a massive fight over dinner at Japanese boite Yamato in Encino, Calif. two nights prior, Gomez, 20, joined Bieber, 18, at a private after party at Bootsy Bellows hosted by Scooter Braun, Bieber's manager. (The pair were photographed inside the Nokia Theatre as well.)
Wearing high-waisted slacks, a white cropped top and black glasses, the "Love You Like a Love Song" chanteuse quietly entered the club with Bieber (wearing all-black plus diamond jewelry) as they made their way to a hidden table in the back room. Surrounded by security, the twosome held onto each other for much of the night and snuck in a few kisses as well.
According to a witness, they were "dancing on each other . . . they seemed to be in great spirits and were clearly enjoying their time together." After several hours, they snuck out of the club's back entrance around 2:30 a.m., speeding off in a chauffeured SUV.
It was a much less lovey-dovey scene at Yamato on Friday. "They had just sat down and didn't order when they started to fight. Ten minutes later, they stormed out without speaking and she drove off in her car," a witness revealed, adding that Bieber was "swearing and yelling" after Gomez's shocking exit.
