After 28 years of living with KISS singer Gene Simmons, it seems like Shannon Tweed -- former model and mother of his two children -- might have finally had enough. During the couple's appearance on The Joy Behar Show, the rocker made a comment that seemed to seriously irk his lady. At that point, it appears Tweed decided she couldn't stand her longtime partner another moment, so she got up and left the studio.

And while speaking to Kathie Lee and Hoda on "Today," Tweed mercilessly skewered the Kiss bassist every chance she had. And when asked specifically about their future, Tweed said, "It's not looking great."

The next time you play Rock Band don't invite Jon Bon Jovi. The 49- year-old singer's wife and kids recently convinced him to give the popular videogame a try. So he picked up the microphone and launched into a rendition of his classic "Wanted Dead or Alive," backed by family on virtual guitars and drums. He never made it through the song.

"I failed--it buzzed me down," Bon Jovi admits over lunch in Manhattan.

Fortunately for Bon Jovi, audiences in real arenas around the world are kinder. His eponymous band took home $125 million over the past 12 months by FORBES' estimates, more than any other music act besides U2--and more than relative whippersnappers Justin Bieber, Katy Perry and Kanye West combined. In the past year the band has played 74 gigs in 15 nations, grossing $203 million in ticket sales and $20 million in merchandise; Bon Jovi ranks No. 8 on this year's Celebrity 100.

Remember last year whenrocker-turned-reality star Bret Michaels covered Poison classic "Every Rose HasIts Thorn" with tween pop queen Miley Cyrus? Well, that's so 2010.

Raine and Jorja sing the song, and Bret plays guitar. The girls are naturals. They perfom the track as a duet as opposed to the choir-like stacked vocals used for most Kidz Bop covers. Their version is acoustic throughout, and is more country than rock. But it's nice.

Kidz Bop asked Bret and hisdaughters to guest on the album, a spokesperson for the record company toldYahoo! Music. Bret was excited. "The mostawesome jobs I've ever had are being a 'Rockstar,' Donald Trump's 'CelebrityApprentice' winner, raising money for kids with Diabetes and, most importantly,being a good father. So

He loves her, yeah, yeah yeah.

Paul McCartney is getting married. The Beatles legend recently announced his engagement to New York businesswoman Nancy Shevell. The news was first published in People magazine, which quoted an unidentified source. McCartney's publicist later confirmed the report.

Almost immediately, online interest in McCartney's future bride zoomed up the charts. Unlike her soon-to-be hubby, there isn't much information about Shevell. According to the official website of her place of work, New England Motor Freight (NEWF), Shevell works as a vice president and is "responsible for accounts receivable, corporate communications, benefits administration, purchasing of all supplies and equipment -- with the exception of trucks -- and overall office management." In other words, she's not in show business.

Again, according to NEWF, Shevell earned her Bachelor's Degree from Arizona State University, where she majored in transportation. She also serves as co-chairperson of the
