Though he was just recently in Australia for his Believe World Tour, Bieber, 18, flew back to Los Angeles to celebrate his girlfriend Selena Gomez‘s 20th birthday at this year’s Teen Choice Awards 2012, where he was also scheduled to perform onstage.
Earlier in the day, the Biebs encouraged fans to send love to his gal, writing on Twitter:
