The rumors never seen to stop in Hollywood. Luckily, "Extra" is always here to set the record straight. From J Lo to Britney, here’s your latest edition of Rumor Control.

She steams up the screen in commercials for her new fragrance, sells millions of records and has her own clothing line, but now could Jennifer Lopez be adding "Wedding Singer" to her résumé?

Yes -- According to reports, Lopez has been approached to sing at the December ceremony for one of the richest women in the world: Athina Onassis Roussel, Aristotle Onassis' granddaughter. She and Alvaro Neto are set to wed in Brazil.

Reports claim that Lopez would donate her performance fee to charity.

Meanwhile, "Extra" got some pictures of Britney Spears' husband and new dad, Kevin Federline, out and about in Los Angeles just weeks after his son’s birth. But is the proud papa taking little Sean Preston wherever he goes?

Yes -- We're told Federline wears a picture of his month-and-a-half-old son around his neck.

And finally, a smiling Cheryl Tiegs posed with her beautiful twin babies and then-husband Rod Stryker a few years back. And in 2000 she couldn't wait to tell "Extra" about her boys, who were conceived by artificial insemination and born to a surrogate mother. But now, is the former cover girl forbidden from ever talking about sons Jaden and Theo?

Yes -- According to the New York Post, that is one of the legal conditions following the couples' divorce. Stryker received full custody of the boys after their 2001 split.
