Singer Mike Posner has dismissed rumours he's Miley Cyrus' new boyfriend, insisting the teenage superstar is too young for him to be dating.
The 22-year-old Please Don't Go star was linked to Cyrus earlier this month (Nov10) after they were spotted together following the MTV Europe Music Awards in Madrid, Spain.
But Posner is adamant he wouldn't date the youngster, who celebrates her 18th birthday on Tuesday (23Nov10).
He tells, "We're not dating. She's a nice girl, but I'm 22-and-a-half!"
Cyrus has since been caught on camera in a Los Angeles club with a mystery man, who has been pictured kissing the singer/actress' neck at her birthday party on Sunday night (21Nov10).
Cyrus recently split from Aussie actor Liam Hemsworth.
