Bieber and Gomez back together. Again.

Justin Bieber cuddled up to Selena Gomez half-naked on Friday night.

The 'Beauty and a Beat' singer - who was dumped by the 20-year-old brunette beauty in December after two tumultuous years together - confirmed he is her "babe" again and posted a new picture on his Instagram profile of the actress sulking as she snuggled into his bare back while he worked on his laptop with the caption: "'You've been makin music for too long babe come cuddle' - her (sic)."
