Jared Followill is engaged to marry Martha Patterson, his band's rep confirms to PEOPLE.
The Kings of Leon bassist, 25, popped the question to the model, 21, on April 11 in Nashville, the rep tells PEOPLE.
Followill and Patterson began dating in January. He was previously linked to Twilight star Ashley Greene.
Followill is the last member of his band to settle down. Brother Nathan wed Jessie Baylin in November 2009, while Caleb married Lily Aldridge in May 2011; they expect their first child this summer. Cousin Matthew and wife Johanna Bennett welcomed son Knox, 1, last April.
