Feisty Rihanna shares a photo of her puckering up to the teen star.
Forgetting about her boyfriend Drake for a minute, Rihanna turned her attention to Justin Bieber.
The 'California King Bed' singer posted a snap of herself kissing Usher's mate, but don't worry Beliebers, she was just smooching his poster.
Leaving the Def Jam studios, Rihanna posed for a peck with the super-sized Justin Bieber cover of Rolling Stone magazine.
"#DefJam I just left the building!! Great s**t RihannaNavy!!" Rihanna posted alongside the pic. "Can't WAIT for this fall."
We hope this means she's been recording new tracks for her follow up to 'Loud'.
