TIGER WOODS and LINDSEY VONN both admitted yesterday that they're a couple.  They simultaneously posted similar messages on Facebook, saying they started off as friends and became closer over the last few months.  They also both posted pictures of themselves together, which were obviously taken from the same photo shoot.

SOFIA VERGARA says her bra size is 32F.  But it's a SAGGY 32F because she's a 40-year-old mom.  She says that in order to make her boobs look perky, quote, "I need [my dresses] to be like an armory.  My dresses are like a work of art inside."

LINDSAY LOHAN copped a plea yesterday on charges that she lied to police after wrecking a Porsche last summer.  She'll spend 90 days in a LOCKDOWN rehab facility.  She'll also do 30 days of community service and undergo 18 months of psychotherapy.  The courtroom video of LINDSAY LOHAN'S hearing yesterday is pretty amusing, because she gets annoyed when her attorney MARK HELLER won't SHUT UP.  At one point when he stood up to talk, she even said, quote, "Oh my God, I'll kill you."  And after the hearing, Heller had to cut his press conference short because Lindsay's dad MICHAEL LOHAN was screaming at him. 

PerezHilton.com claims the BLACK EYED PEAS are replacing FERGIE . . . temporarily.  A "source" says the group is, quote, "secretly" auditioning female singers right now.  Supposedly, Fergie, who's pregnant, wants to take some time off . . . and she'd be free to return to the group when she's ready.
