By the sounds of it, Noel Gallagher is a regular visitor to the south of France as he's previously discussed hanging out with Bono and U2 in that part of the world.

It's hard to imagine the funniest man in rock being star-struck around anyone, but he found himself rubbing shoulders with an unlikely person at a recent lunch at a friend's house - none other than the legendary Robert De Niro.

He captioned the picture, posted to Instagram: "So we've been down to The South Of France for a few days and at 17 hour lunch at our friends house THIS..THIS.. Actually happened!!!"

It would make sense if the 'friend' in question was, indeed, Bono, as he has a house there and has been known to hang around with De Niro in the past, with a source telling E! News that "Bono and Robert De Niro are really good friends and they hang out in the South of France together every summer,” as far back as 2008.

What we're more interested in is WHAT ON EARTH DID THEY TALK ABOUT?

And more importantly, what does Liam think about it?
