Prince Harry was distracted by Gaga's revealing outfit
Harry was caught glimpsing directly Gaga’s chest, as he awkwardly cosied up to her, ahead of the WellChild concert, which saw her and Tony play hits from their jazz album ‘Cheek To Cheek’.
Gaga was looking stunning in a plunging floor-length silver sequined dress by Brandon Maxwell, with matching diamanté eyebrows.

According to The Mirror, they could be heard chatting about Harry’s mum Diana, with Tony telling the Prince: "Your mum was a good friend of mine, I did many benefits with her."
“That's fantastic,” he replied.
Harry was at the gig as he has been a patron of the WellChild charity since 2007, and has gotten to know many of seriously ill children and their families that they help.
