• It's been a busy 24 hours for Tiger Woods. Just after admitting he'd "let his family down" yesterday, a voicemail he apparently left for alleged mistress Jaimee Grubbs surfaced and put a nail in his adulterous coffin. Now Rachel Uchitel, one of the other women he supposedly was involved with, is coming clean about her affair and will be giving a press conference later today. [TMZ, NYP]
• Meanwhile, Tiger and wife Elin are supposedly in "intense" marriage counseling. They're also in intense discussions with their lawyers, apparently. Rumor has it they're renegotiating their pre-nup and Elin may collect a "hefty seven-figure amount" if she agrees to stay with him. [CST, Us]
• Tinsley Mortimer's family sounds more white trash than high society. Her mom, Dale Mercer, got into a shoving match recently with the woman who's been dating her ex-husband. George Mercer—Tinsley's dad—says the 29-year-old woman, Krissy Morrow, is merely his "escort" and he's never even kissed her. But Krissy says she married Mercer last month. George says the marriage didn't count since he was "drunk as [expletive]" at the time and because he's married to someone else anyway. Let's hope all this nonsense—like the report Tinsley was seen making out with Constantine Maroulis on Tuesday night—is just another PR stunt for her reality show. [P6]
