Don't they look like they're having an absolute hoot? They totally dropped in for an impromptu pint, it wasn't scheduled via several souls and then the candid shots weren't signed off on, which is quite refreshing.
The pub in question was in Notting Hill. The A-list pals opted against expensive restaurants and private members' clubs, instead meeting in Irish pub The Cow, and their visit sent regulars into a frenzy.
Patron Lisa Freid, who "couldn't believe" her eyes, snapped a sneaky picture which she posted on her Instagram.
She captioned said photo with "#london #pub #nottinghill #beckham #tomcruise #wtf #justnexttous #chilling #monday."
Another Instagram user also took a picture of the actor and soccer star, writing: "Another Monday night at the pub with David and Tom."
Tom, 51, and David, 39, shared a bottle of wine, while the retired soccer star was also seen nursing a pint of Guinness. That, by stats recently released, constitutes a binge session. Just saying.
For those of you fervently knocking about the Notting Hill area trying to bump into Tom Cruise, he's since headed off to Japan to sign approximately a million autographs in Kansai International Airport in Osaka.
The Mission: Impossible actor and Beckham became "incredibly close" when himself and Victoria moved to Los Angeles in 2007, when the soccer ace was signed by the LA Galaxy soccer team.
David recently confessed he and Tom held regular movie nights while he lived in the sunny city with his family.
He said: "When we were living in LA, Tom Cruise lived two minutes away. He's a good friend. There were occasions when I'd call him up and ask him if he had a new movie that wasn't out yet, and I'd go round and watch it with him."
Anyone else picturing them in matching onesies right about now? Just the crisp white manties? OK, we'll go with that.
