New rumors are making the rounds of Hollywood today, and we're here to separate the truth from the chatter.

First off, who wants to be a newlywed? Could it be Kevin and Britney?

Yes -- according to Us Weekly's Shirley Halperin, the singer and her dream dancer are talking with MTV about becoming the next "Newlyweds," following in the footsteps of Jessica and Nick with their own "Newlyweds" reality show.

"It would be more like a staged show," Halperin told us. "Not like the real nitty-gritty you got from Nick and Jessica's show."

Despite a report that Spears and Federline are about to split, Us Weekly says the two are still planning to get married. Moreover, they say the pop princess can't wait to have her first year of marriage filmed, and wants to make a star out of her husband-to-be.

"She wants to have Kevin's name be more of a name," said Halperin. "(To) just let him stand on his own and get his own attention."

Meanwhile, Keanu Reeves is one of Hollywood's hottest stars and most eligible bachelors, so now, at 39, is he finally ready to settle down and tie the knot with his girlfriend, actress Autumn Macintosh?

No -- Keanu himself came to "Extra" to set the record straight, telling us he's not ready to walk down the aisle. Despite a report of wedding bells, for now Mr. Matrix is happy playing the role of the bachelor.

Is the self-proclaimed Queen of Plastic Surgery, Joan Rivers, turning her real life into a TV role?

Yes -- we discovered that Joan is set to guest star as a patient on the season finale of FX's hit drama, "Nip/Tuck," playing -- who else? -- herself.

A recent photograph of Christina Aguilera holding her stomach sparked rumors that she's pregnant and suffering from morning sickness -- so is the sexy songbird with child?

No -- Christina's spokesperson tells us that, although the singer was not feeling well last week, she is definitely not pregnant.
