Jack Osbourne has proposed to his girlfriend Lisa Stelly.
The 25-year-old reality TV star - son of rocker Ozzy Osbourne - asked the model and aspiring actress to marry him and she has announced their engagement on Twitter.
Lisa wrote: "The most amazing man I've ever met asked me to marry him... and he wasn't joking! Crazy, right."
Jack - who has previously been linked to Taylor Momsen and Kimberly Stewart - rose to fame in 2002 when he and his sister Kelly starred alongside their parents Ozzy and Sharon in MTV reality show The Osbournes.
He has since appeared in several reality shows but has also done work behind the camera.
Jack directed Ozzy's music video for the song Life Won't Wait in 2010 and earlier this year produced a documentary about the Black Sabbath rocker, God Bless Ozzy Osbourne.
It has also been reported that Jack is training to become a policeman.
On July 1, he posted a picture of himself on Twitter in a police uniform, with the caption: "Another day at the office."
A friend of Lisa's told Us Weekly Jack is "a great influence on her," adding: "It's just no drama. More stable."
