Rachel Uchitel I'm Leaving the Door Open for Tiger ...If He Grovels

Call it kismet, or karma, or whatever ... there's a chance Rachel Uchitel and Tiger Woods will go another round.

Rachel tells us she just broke up with baseball star Bret Boone, days after Tiger called it quits with Lindsey Vonn.

So the question ... does Mistress #1 still have a hankerin' for the golfer with a roving eye?

Sources close to Rachel say she told them, "We both loved each other very much," but adding, "It was humiliating and devastating to have to break up that way."

Now the opening ... Rachel says, "He would have to do some major apologizing to get back in my good graces, that's for sure."

No word from Tiger, but remember, when he was banging Rachel he was at the top of his game.

Tiger Woods & Lindsey Vonn DUNZO

Chalk up another loss for Tiger Woods ... this time, it's his girlfriend -- 'cause Lindsey Vonn just announced the couple has officially broken up.

The world champion skier broke the news on Facebook ... saying, "After nearly three years together, Tiger and I have mutually decided to end our relationship."

"I will always cherish the memories that we've created together. Unfortunately, we both lead incredibly hectic lives that force us to spend a majority of our time apart."

"I will always admire and respect Tiger. He and his beautiful family will always hold a special place in my heart."

Probably for the best ... since she just went on "Late Night with Seth Meyers" and admitted she hates golf.

The athletic lovebirds are really committed ... to getting those kids to class on time.

Lindsey Vonn Playing Mom Taking Tiger's Kids to School

Lindsey Vonn might be in it with Tiger Woods for the long haul ... because she was spotted this morning taking his kids to school ... with no sign of Tiger.

The two awkwardly announced their relationship via Facebook back in March, saying they have "been friends for some time, but over the last few months we have become very close and are now dating."

That means their relationship is somewhere around the 5 or 6 month mark.

So, we gotta ask ...

Tiger Woods & Lindsey Vonn The Topless Boat Party

Tiger Woods lost the shirt off his back ... and this time his ex-wife Elin Nordegren had nothing to do with it.

While his fancy schmancy boat is called Solitude, Tiger spent the afternoon lounging and fishing with his two adorable kids and his sexy bikini-clad girlfriend Lindsey Vonn yesterday.

Although he's no stranger to being in the heat, hopefully Tiger used protection.

Tiger Woods & Lindsey Vonn Holding Hands in Public!

This is the sports super couple's first public display of affection since revealing they were bangin' by posting cheesy pics together on Facebook back in March.

In a glimpse of what may lie in their near future, Lindsey wore a virginal white gown as they walked down an aisle together.

Ironically, Tiger's next gig is competing in The Players Championship ... something he knows all about.

Lindsey Vonn Tailing Tiger At The Masters

Might as well tailor that green jacket for Tiger Woods ... 'cause his 5'10" blonde good luck piece -- aka Lindsey Vonn -- showed up for round one of The Masters.

LV turned up at Augusta National to support her man wearing a giant floppy hat ... perhaps to make sure cameras can find her all day while she follows Tiger?

We're betting Tiger doesn't care what she wears 'cause he's been on a tear since going public about banging Lindsey -- winning two tournaments in a row, and 3 out of his last 5.

So, if Tiger wins his 5th Masters on Sunday ... she can probably expect a wedding ring (not that it means anything).

Tiger Woods The $60M House That Elin Didn't Get

Now that he's confirmed he's dating 28-year-old Olympic skier Lindsey Vonn, Tiger Woods has his choice of rooms to make the magic happen in his sick $60 million mega estate.

Tiger's ridiculous waterfront crib on Florida's exclusive Jupiter Island comes with all the bare necessities for an athletic super couple to work up a sweat together ... like a tennis court, diving pool and lap pool, running track, boat slip and the ubiquitous backyard golf course.

Lindsey will no doubt enjoy her time being the mistress of the house.

Tiger Woods Ex-Mistress I Bet He's Already Cheating on Lindsey Vonn

Once a cheater, always a cheater ... so says a former Tiger Woods mistress who tells TMZ Tiger's new GF Lindsey Vonn better know what she's getting herself into.

We spoke to former hooker/porn star/ Devon James -- who tells us she was shocked when she saw the pics of Tiger and Lindsey on Facebook yesterday ... saying, "I thought he would have picked a woman who was more petite and not someone who is more muscular and has a bigger head than his."

James continues, "But maybe his taste has changed since Elin and the 27 mistresses."

"But you know when the pics came out of Tiger and his new girlfriend ... somewhere, 15 other girls were going , 'Huh? I thought I was his GF!'"

Think James has a point ... or is Tiger a changed man?
