Ozzy Osbourne's son Jack has sparked speculation his wedding is imminent after heading to Las Vegas for his bachelor party this weekend (22-23Sep12).
The reality TV star proposed to girlfriend Lisa Stelly last year (11) and they became first-time parents to daughter Pearl in April (12).
The 26 year old revealed in June (12) he had been diagnosed with multiple sclerosis, but insisted he was focusing on his nuptials to take his mind off his health scare - and now it appears the wedding is approaching.
In a post on his Twitter.com page on Saturday (22Sep12), Osbourne writes, "Let the games begin! Palazzo (hotel) Las Vegas bachelor party."
Stelly also uploaded photographs from her bachelorette bash showing her in a burlesque costume, complete with a white bobbed wig and matching feather boa.
The bride-to-be revealed her fiance's sister Kelly had given her a saucy gift: "Thanks Miss Kelly O for my diamond encrusted riding crop. I'm obsessed with it, I can't put it down."
She also poked fun at her partner's celebrations, adding: "My bachelorette party is better than your bachelor party Mr Jack O. Best party ever! Woo hoo!"
Osbourne replied by posting a picture of himself wearing a casual outfit and baseball cap alongside the caption, "Well wife to be... I think mine is about to get a whole lot crazier then yours."
