Help John Mellencamp Quit Smoking

You can help John Mellencamp kick his smoking habit: Join his son Speck's Facebook group, which he's pledged will make him stop once and for all.

Speck, 14, writes on the Facebook page, "i made a deal with my dad that if i get a 1,000,000 to join this group he will quit smoking."

The "Jack and Diane" singer should prepare for cold turkey — within a day of its launch the group gained 60,000 members, and is fast moving toward his target.

His 58-year-old father has talked openly about trying to kick his decades-old habit, despite having a heart attack in 1994.
