Breakups do a body good ... especially for Elin Nordegren ... who was flaunting her bikini hardbody just days after ending things with her Tiger Woods rebound guy Jamie Dingman.

The Swedish 32-year-old mother of two was hanging out in Miami this weekend ... after announcing her 1-year relationship with the wealthy businessman officially hit the skids.

Since divorcing Tiger, Elin has been busy buying a new $12 million North Palm Beach estate and then leveling it to build her dream home from the ground up.

Elin definitely looks like $100 million bucks.

Everyone knows ... nothing attracts hot, young naked women like a badass grotto (just ask Hugh Hefner) which might be why Elin Nordegren is officially SCRAPPING plans to build one at her post-Tiger Florida mansion.

TMZ has learned ... Elin's engineer has filed documents to alter the specs on her multi-million dollar mansion re-building project in North Palm Beach.

In the docs, the engineer notes that Elin has decided to 86 the pool grotto and make a "slight reconfiguration" in the shape of the pool.

As we previously reported, Elin bought the place for a cool $12.5 mil ... then leveled it to build her dream home from the ground up. Clearly, money is not an issue.

For the record, Hugh Hefner has several mattresses surrounding his grotto ... for naps.

Naps.

Elin Nordegren is SO rich -- she's basically building a replica of the multimillion dollar estate she knocked down. 

TMZ has obtained renderings Elin submitted to the Palm Beach County Dept. of Planning, Zoning & Building.  The exterior elevation drawing is verrrry similar to the house that was on the $12 million property before Elin razed it. Both are traditional/colonial homes with a very similar shape.  The drawing looks similar to the 9,000 square foot house that was demolished.

Elin's builder told PEOPLE the house Elin 86'd was 90 years old, didn't meet code provisions to withstand hurricanes, and was infested with termites.

Of course, the house Elin builds will be brand spanking new. The supporting documents describe the house in detail. 

-- 9 bedrooms
-- 2 large living rooms
-- huge formal dining room
-- 2 kitchens
-- large pool
-- GROTTO!!!
-- pool cabana with HUGE living room
-- 2 jacuzzis
-- detached guest house with 3 bedrooms
-- 3 guest bungalows
-- wine cellar
-- ginormous master wing with crazy big walk in closet
-- basement that runs the entire length of the house

There's 120 feet of retaining walls, and they are bringing in 4100 cubic yards of soil -- which is an enormous amount. 

County officials have sent the architect back to the drawing board for some changes before the plans will be approved.

Elin Nordegren is a human wrecking machine ... who just LEVELED her brand new $12 MILLION Florida mansion ... because, well, she can afford it.

Elin bought the 9,000 square foot North Palm Beach home in March ... right after she struck a $100 million divorce settlement with Tiger Woods.

Apparently, Elin felt the modest 6 bedroom, 8 bathroom pad wasn't quite up to her standards ... so she did the only reasonable thing -- KNOCKED THE WHOLE PLACE DOWN!

We're told Nordegren has hired a high-priced architect to build her dream home ... and sources say every single worker is required to sign a confidentiality agreement.

No word on how long the project is expected to take -- but we're told Elin is living in a nearby mansion inside the private community while the new place is under construction.

It's good to be rich.

Tiger Woods wasn't the only living creature whose life was ruined on that fateful night in November 2009 -- the tree he crashed his Escalade into has been murdered ... TMZ has learned.

Sources close to the tree tell us ... new neighbors moved in recently and began remodeling -- and one of the first things they did was tear down the infamous oak tree.

The construction company that did the job tells us the tree was in bad shape ever since the crash -- and even though the new neighbors knew full well the tree's place in history, they decided to get rid of it anyway.

And don't think the tree will be showing up on eBay anytime soon -- it was NOT saved, it was simply trashed.

We're told a new tree will be planted soon, but in the meantime ... there's a Porta-Potty in its place.

Symbolic of where Tiger's career has gone, don't you think?

The same day he announced his split from his longtime caddie, Tiger Woods nursed his knee and leg injuries on a 61-foot yacht off the coast of Jupiter Island, Florida ... alongside his children.


The photos were taken on Wednesday -- while Tiger was aboard his ultra-private yacht named Solitude.  The boat was reportedly custom built for Elin ... and cost somewhere in the neighborhood of $2-3 million.

It appears Tiger got to keep the boat.

As for the mystery woman on the ship -- we're told she's Tiger's nanny ... and not a love interest.

Sources tell TMZ the gang spent half the day fishing and diving off the boat ... because they can.

Elin Nordegren is PISSED ... after learning Rachel Uchitel told friends she had slept with BF Jamie Dingman. Now Jamie is denying it happened, but others are providing VERY specific details.


Sources tell TMZ ... Elin was blindsided when the TMZ story ran over the weekend ... that Tiger Woods' #1 mistress had slept with Jamie and Elin didn't know about it.

We reported Jamie hooked up with Rachel twice in Miami in October, 2009,  when they were staying together-- less than 2 months before the scandal broke.  Jamie's friends now tell TMZ ... Rachel is lying and that they never had sex and never stayed together.

But  other people familiar with the situation tell TMZ ... Rachel and Jamie went down to Miami in October, 2009, to work on a plan for a new investment business.

Click here... it's not over yet

Elin Nordegren may be in Sweden, but she just can't seem to escape Rachel Uchitel -- because we found out ... Rachel banged Elin's new boyfriend!


We told you yesterday ... Tiger Woods ex-wife is dating marketing exec Jamie Dingman, whose dad is a billionaire tycoon. But before Elin, sources tell TMZ Jamie and Rachel were an item -- and there was a little bit of an overlap with Jamie and Tiger, but Jamie bowed out to the golfer.

In fact, when Rachael got serious with Tiger, Jamie joked with her, "That ok.  I'll date his wife, Elin."

And get this ... at the time the Tiger Woods scandal broke, Jamie was living with Rachel in a MIami home. 

And there's more. Remember the name, Jen Madden? She's the one who sold the Tiger Woods story in the first place, and she got the info because she stayed at the Miami home and overheard Rachel tell Jamie about her affair with Tiger.

Who knew Elin Nordegren had a little bit of Rachel in her.

It appears Elin Nordegren has found another man, after divorcing Tiger Woods.


The guy is Jamie Dingman, a New York marketing exec. 

A Swedish photo agency came to TMZ with what they said was a photo of the two, kissing and hugging outside Elin's apartment in Sweden.  TMZ has seen the photo -- but the agency decided it wanted to hold it ... at least for now.

Jamie's dad, Michael Dingman, is a very wealthy investor.  Jamie specialized in Russian private equity funds and he also owned an Indy car-racing team.

He reportedly dated Bridget Moynahan, Tom Brady's baby mama.  He was also linked to Princess Madeleine of Sweden, but the New York Post says they were just friends. It does, however, provide a Swedish connection.

The photos have appeared on a Swedish website Expressen.tv as part of a video package. Good luck translating.

Elin Nordegren has reportedly used some of her $100 million divorce settlement from Tiger Woods to buy a brand new $12 million home ... just ten miles from Tiger's new digs.


The 9,000 sq ft beach front home in North Palm Beach features eight bathrooms and a 4,000 sq ft basement.

Elin is the only mistress of this house.

Tiger Woods didn't spend Christmas day alone this year -- truth be told, he hung out with 19,000 people.



TMZ snagged these photos of Woods sitting courtside at yesterday's Orlando Magic/Boston Celtics game in Florida -- while Elin Nordegren and their two kids were far away, celebrating the holidays Swedish style.

If the kids aren't back for New Year's Eve -- he could always go to the Oklahoma Thunder/Atlanta Hawks that night... or bump into Rachel Uchitel at Donald Trump's party. 

Tiger ... door #1 is a lot safer.
