Jared Followill and Martha Patterson are planning a low-key wedding.

The Kings of Leon bassist proposed to model Martha on April 11 at his home in Nashville, after just a few months of dating and the pair are hoping to tie the knot in front of a small group of friends and family soon.

A source told Us Weekly magazine: ''They're excited and a bit nervous. They've dreamed up a family affair with homespun and rustic details. Jared picked the perfect woman to settle down with.''

Jared, 25, popped the question with a four-carat cushion-cut diamond, set on a diamond band, which he designed himself.

His representative announced the engagement saying: ''Yes, it's true! Jared proposed to Martha on April 11 at his home in Nashville and we're all excited for the newly engaged couple.''

Jared also wrote on his twitter page: ''It's true! I'm engaged! CANNOT wait to finally lose my virginity (sic).''

Jared's brother and bandmate Nathan is currently expecting his first child with wife Jessie Baylin, while their other sibling Caleb - the group's singer - and his wife Lily Aldridge welcomed daughter Dixie Pearl into the world in June.
