Birthday boy Justin Biebershowed his appreciation to GFSelena Gomez with a smacker after she flew in for his 18th party on Friday night.
The loved-up couple tweeted a series of snaps of themselves smooching at Biebs' bash in Los Angeles.
Selena, 19, had been filming movie Spring Breakers in Miami with Vanessa Hudgens, but jetted across the US to be there for her BF's big night - having missed a meal on his actual birthday night in the week.

And we reckon Biebs must have enjoyed himself because he tweeted "NO MATTER WHAT WE PARTY TONIGHT" and "#greatnight".
Earlier in the week he appeared on Ellen and revealed that [uuid=ace8001f-d5da-46ec-816e-a911cf98ce7d]his next single[/uuid] would be called Boyfriend.
