What do these five people have in common with Tinsley Mortimer's dad, George Mercer? Absolutely nothing, but they were all witnesses of Michael Fredo's ill-fated jazz set at the Plaza Hotel's Rose Bar. Who in their right mind compiled this guest list?

• Tiger Woods' mistress tally is quickly approaching the double digits. Jamie Jungers, a Las Vegas model, says she had a two-year affair with Woods; then there's Cori Rist, an aspiring model, who says she started seeing Woods after meeting him at Butter. To top it all off, porn star Holly Sampson has also been mentioned as a woman Woods was involved with, although she's yet to confirm or deny the report. Meanwhile, Queen Oprah thoughtfully reached out to Tiger over the weekend and offered him the opportunity to tell his side of the story, and that may be his best chance yet of somehow saving his rep at this point.

• Alexa Joel, the daughter of Billy Joel and Christie Brinkley, is recovering at home after what seems to have been a suicide attempt on Saturday. Joel took a bunch of homeopathic sleeping pills—possibly because she was upset over a break-up—and then called 911 herself. [NYP, NYDN, NYP]

Who hasn't slept with Tiger Woods? An actress who debuted in The Wonder Years, then went on to OMG Stop Tickling Me joins Tiger's stable; Lohan looks surprisingly hot in a faux-threesome; reality stars eat rats. Monday gossip ahoy!

• 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]
