Most women would be thrilled to see Justin Timberlake's tush, but it's all in a day's work for Madonna. While speaking at Madge's Rock and Roll Hall of Fame induction earlier this month, JT bragged that the Queen of Pop made him drop trough to give him a vitamin B12 shot while they were collaborating on her upcoming album, Hard Candy. ("That was one of the greatest days of my life," he joked.)

But Madonna (who is technically old enough to be a young mom to Justin) didn't think of it as a big deal at all. "The reason I gave him a B-12 [shot] is because we only had a certain amount of days in the studio and I didn't want him to use that as a lame excuse not to come to work," she told New York's Z100-FM. "OK? It's got nothing to do with butt. I promise you. Listen, I don't need to give him a shot to see his butt. Duh." We wish we were that lucky!
