Guy Parties Late Night Minus Madonna

Madonna calls it quits early on, but Guy Ritchie continues celebrating his 40th birthday until 4 a.m.

Maybe Madonna really is getting old?

At her hubby Guy Ritchie's 40th birthday bash last night, Madge couldn't hang past 10 p.m. Guy was snapped helping his wobbly wife to the car before heading back inside The Punchbowl and continuing to party until 4 a.m.!

Of course, she may just be tired from touring...she performed Tuesday night in Frankfurt, Germany and has another show tonight.

But it looks like Guy had enough fun for both of them. He was making goofy faces at the paparazzi through the windows and heard having a late night singalong.
