Now three years past the deadline in his famous song, the music legend is very much assured of his girlfriend's devotion as was clear at a recent baseball game.
Despite him being wrapped up in the sporting action at the Yankees stadium, he didn't go hungry.
The attractive American – whom he's been dating for two years – was seen offering him bites to eat from her own plate during the match.
She also had no problem sharing him with some male friends, happily chatting away with his pals Jack Nicholson and TV producer Lorne Michaels, who introduced him to the game.

Forty-seven-year-old Nancy got her reward for sticking with it up till then, with Macca pulling her in for a lingering kiss and cuddle before she left.
