Someone came down with a wicked case of Bieber fever!

Justin Bieber has always had serious swagger, and he proved it by hooking up with newly single Victoria's Secret supermodel Adriana Lima at Cannes!

The Biebs was apparently dead set on bagging the cat walker, and set about making it happen the minute he touched down at the film fest!

"Justin pursued her hard," a source tells Us Weekly, adding that the pair were "talking nonstop" at the 1 Oak fete before going home together at 5am. Oh la la!

JB might be twelve years her junior, but apparently the Brazilian beauty couldn't resist his charms. The "Boyfriend" crooner posted a snap with the sexy stunner with the caption, "I think she foreign, I think she foreign", a reference to some of his lyrics.

The Canadian sensation is really adding notches to the bed post these days!
