Jack Osbourne and Friends Hit Las Vegas For an 'Unorthodox' Bachelor Party (EXCLUSIVE DETAILS)
Keep an ear out for some heavy metal wedding bells.
New father Jack Osbourne -- son of the Prince of Darkness Ozzy Osbourne and The Talk host Sharon Osbourne -- has celebrated his final days as a bachelor.
The 26-year-old kicked off his bachelor party last Thursday in true Hangover style with a road trip to Las Vegas, Nev. where the English media personality shacked up at the The Palazzo Hotel.
"They drove from Los Angeles to Sin City to spend a guys weekend," an insider told Celebuzz.
But that's where the similarities to Phil, Stu, Alan and Doug end.
There was no Tiger, nor Tyson. Indeed, the son of a notorious heavy metal icon shunned nightclubs in favor of quality time with his pals, the source added.
How can you have a fun bachelor party in Sin City and be well behaved?
"On Saturday, Jack's party headed to Azure Pool at The Palazzo where they had a private cabana and just enjoyed the Vegas sun," the source revealed.
"Then, the group headed to Lagasse Stadium for Oktoberfest."
The bachelor party then combined every man's favorite three favorite things: Beer (or in Osbourne's case, soda), bratwurst sausages and college football.
The team skipped the traditional bachelor rite of passage -- strip clubs -- as well.
"It wasn’t a regular Vegas bachelor party," the source said. "They even went to bed very early, waking up early around 7 AM to go hiking and ATVing.
"It was more of an adventure bachelor party. Unorthodox, if you can believe it."
Osbourne's fiancee, Lisa Stelly, had a slightly more wild bachelorette party.
The new mom -- the couple's first child Pearl is five-months-old -- donned super sexy white lingerie and recieved naughty gifts from friends at her event.
Soon-to-be sister in-law, E! Fashion Police panelist Kelly Osbourne, gave Stelly, 27, one of her favorite gifts.
"Thanks @MissKellyO for my diamond encrusted riding crop," the soon-to-be Osbourne tweeted. "I'm obsessed with it, I can't put it down."
The upcoming wedding will be a well-deserved celebration for Osbourne, who was recently diagnosed with multiple sclerosis, an autoimmune disease, which causes the body to attack itself.
