Kings of Leon drummer Nathan Followill married girlfriend singer/songwriter Jessie Baylin over the weekend. UsMagazine.com reported that Followill, 30, and Baylin, 25, married on Saturday evening at Wolf Den Farm in Brentwood, Tennessee, in a small ceremony that included close friends and family, as well as actress Scarlett Johansson, a high school friend of Baylin's.

"The wedding was beautiful. It was a gorgeous, 70-degree day," an unnamed band rep told Us of the ceremony, which took place in a rustic barn. Baylin, who was born in New Jersey but lives in Nashville, has released two albums of rootsy music, including last year's Firesight. The couple first met at the Bonnaroo festival in 2006.

Followill, 30, tweeted about his wedding on Sunday morning, according to People.com. "I woke up with a married woman in my bed this morning," he wrote. "Luckily she was mine."

The wedding caps a stellar year for the Kings, who have long been popular overseas, but had struggled to build a large U.S. audience until recently. In addition to a smash headlining tour of amphitheaters, the Kings snagged a Grammy award for their breakthrough hit single, "Sex on Fire," from their most successful album to date, Only By the Night, which has sold more than 7 million copies worldwide.

After years of being notorious hell-raisers on the road, Nathan is the first of the Followills — the band is led by middle brother, guitarist/singer Caleb, and features youngest brother Jared on bass and cousin Matthew on lead guitar — to wed. The Kings recently released a live DVD and have talked about releasing a remix album featuring the deft touches of Justin Timberlake, Linkin Park and Pharrell.
