Kings Of Leon rocker NATHAN FOLLOWILL is engaged after proposing to his girlfriend at her parents' restaurant, in front of all her family and friends. The drummer has bet his brother and bandmate Caleb Followill $100,000 (GBP50,000) he'll never have sex with another woman, apart from his wife-to-be, again. He tells, "I got engaged two nights ago. It (the proposal) was the first time my mom had ever met her parents." Caleb adds, "He's made a $100,000 bet with me that he'll never sleep with another woman."
