There's a 60-year age gap between them - but that hasn't stopped Lady Gaga and Tony Bennett teaming up for a duet.

The duo sing together for a cover of the classic The Lady is a Tramp for Bennett's latest album Duets 2.

In the video, Gaga hams it up with her died blue hair, drinking wine, flirting with Bennett and playfully removing his red handkerchief.

She even gives him a peck on the cheek at the end of the clip.
