Who is Britney's new fella? The New York Post's Page Six says that the gent Spears has been spied out with, most recently necking in public this past Sunday night, is Jonathan "J.R." Rotem, a multiplatinum music producer who has worked with Rihanna, 50 Cent, Paris Hilton and, oh yeah, Kevin Federline.... Tori Spelling and husband Dean McDermott's first child together will be a boy, and "his middle name will be Aaron," Spelling tells People.... Jenna Jameson filed court papers on Monday seeking legal separation from Jay Grdina, her hubby of three years and a fellow adult-film star, Reuters reports. Estranged from Grdina since July 1, Jameson has been dating ultimate-fighting champ Tito Ortiz for several months - but still hasn't let him get to second base, rumor has it.
