Has Britney Spears' wedding turned into a nuptial nightmare? Did 58-year-old Cher find love in a much younger guy? And where do Beyoncé and Jay-Z and Matt Damon and his girlfriend vacation? Here are all the answers.

Britney Spears and fiancé Kevin Federline are facing an all-too-familiar problem -- fighting through the headaches of planning their wedding day. The couple is reportedly expected to say their "I do’s" in November, but in the upcoming issue of Us Weekly, Senior Editor Joey Bartolomeo reports there’s a lot of confusion about who will be on the guest list when the pair ties the knot.

"She just wants family and close friends to be there, a nice intimate gathering," Bartolomeo explained. He also says that although Spears can’t wait to settle down, she’s made one vow already: Britney and Kevin promised not to get impatient and run off to Vegas to get hitched.

According to a published report, Cher may have found love at 58. The star is being linked to Calvin Klein model Gabriel Aubry, who’s in his mid-20s. We contacted Cher’s people, and they didn’t confirm or deny the reports.

Ever wonder where the rich and famous unwind? Well, Beyoncé Knowles and her boyfriend, rapper Jay-Z, relaxed in Monte Carlo. Beyoncé wore a golden bikini, showing off her ultra-fit body. Later, she took a stroll in town, sporting a sexy blouse and snake necklace. Jay-Z also had some fun with photographers, grabbing a camera and snapping some pictures of them.

Next stop for the super couple: the VMAs in Miami, where both are nominated.

Matt Damon and his new girlfriend, Luciana Borroso, are on a working vacation of their own. The couple showed up to the premiere of "The Bourne Supremacy" in Sydney, Australia. Damon left Borroso's side only for a moment to take a cell phone call from a fan.
