The bass player popped the question to aspiring model Martha Patterson - who he has been dating for a few months - on April 11 at his home in Nashville, Tennessee, with a ring he designed himself.
The 25-year-old musician got down on one knee with a four-carat cushion-cut diamond, set on a diamond band.
Jared - who previously dated 'Twilight' actress Ashley Greene - took to his twitter account to confirm he is engaged to Martha.
He wrote: ''It's true! I'm engaged! CANNOT wait to finally lose my virginity (sic)''
And his representative told JustJared.com: ''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.''
The pair plan to split their time between their homes in Nashville and Los Angeles, but the couple's wedding date is yet to be revealed.
Jared recently posted a picture of the pair kissing on twitter.
