Jack Osbourne Engaged To Actress Lisa Stelly

Girlfriend announces engagement to former star of MTV's 'The Osbournes' via Twitter.

Jack Osbourne is ready to tie the knot! The former MTV reality star popped the question to girlfriend Lisa Stelly after dating for four months.

The heir to the throne of darkness is "a great influence on her. It's just no drama. More stable," a source told Us Weekly about the duo.

Over the summer, Jack appeared on Howard Stern's show to talk about a documentary he was making about his father, Ozzy Osbourne, and also chatted about his relationship.

Stelly took to her Twitter account on Thursday night to share the good news: "The most amazing man I've ever met asked me to marry him....and he wasn't joking! Crazy, right?"

While 24-year-old aspiring actress Stelly's résumé is still light, Osbourne has maintained a presence in Hollywood since he appeared with his family on the hit MTV series "The Osbournes." The reality show had an impressive three-year run before ending in 2005. Jack later starred in his own U.K. reality show, "Jack Osbourne: Adrenaline Junkie," for two seasons.

The 25-year-old has been keeping busy making television appearances on shows like "Armed & Famous" and "I'm a Celebrity, Get Me Out of Here! NOW!" The family even tried their hand at variety TV in 2009 with Fox's "Osbournes Reloaded." The show lasted just one season.

Osbourne, who has spoken out about his battles with substance abuse over the years, documented his dad Ozzy's life, including his struggles with drugs and alcohol, in the 2011 film "God Bless Ozzy Osbourne."

Share your congratulations for the couple in the comments!
