Paul McCartney is 69 years old, but the legendary ex-Beatle has somehow managed to stay hip -- until now. Sir Paul has named his upcoming album "Kisses on the Bottom." No, this is not a joke. He's confirmed it.

While the title recalls painful memories of Ben Affleck kissing Jennifer Lopez's famous rear end in her video for "Jenny From the Block," McCartney explains on his website that the name comes from the lyrics of "I'm Gonna Sit Right Down And Write Myself A Letter," the song popularized by Fats Waller in 1935:

"I'm gonna sit right down and write myself a letter and make believe it came from you; I'm gonna write words oh so sweet. They're gonna knock me off of my feet. A lot of kisses on the bottom, I'll be glad I got 'em,'" the lyrics read. OK, so that makes it a little better...

McCartney also describes the album, in stores next month, as "a deeply personal journey through classic American compositions that, in some cases, a young Paul first heard his father perform on piano at home." It also includes two new tracks and features Diana Krall, Eric Clapton and Stevie Wonder.

Nice try, Paul, but this album title is a bit too distracting for us to focus on the music. And perhaps you're a bit too distracted by your new bride's bottom. In honor of the terrible title, NME music magazine came up with a "50 worst album titles in history" list. Let us know: What's the worst album title of all time?
