Bad blood: Tiger Woods' exes still at odds

Both of Tiger Woods’ exes, Elin Nordegren and former girlfriend Lindsey Vonn, were making the rounds over Kentucky Derby weekend — and party organizers were ordered to keep the two blondes apart.

While Nordegren and Vonn have been friendly in the past, party organizers were instructed not to seat the Olympic skier anywhere near the former Mrs. Woods, we hear.

The pair crossed paths a night before the big race at Friday’s Barnstable Brown Foundation Gala, which was also attended by Kate Upton, Jon Voight and Megyn Kelly.

We’re told Swedish beauty Nordegren, who divorced Woods in 2010 after his myriad affairs were uncovered, then headed to breeder Black Rock Thoroughbreds’ Fillies & Stallions party to join guests including Green Bay Packers quarterback Aaron Rodgers and singer Joey Fatone, with Vonn arriving not far behind.

“The staff was being told over a walkie-talkie that Lindsey was on her way over and must be put in a different area from Elin,” said a source. “They were very clear about that.”

Vonn — who dated the golf superstar from March 2013 until May 2015 — had problems getting into the event because she had been issued the wrong wristband. But once inside, we’re told she sat with girlfriends in a separate VIP area, well away from the mother of Woods’ two children, Sam and Charlie.

According to insiders, former gold medalist Vonn was also very insistent that she didn’t want photographers to take her picture at the fête.

We’re told the two women have a complicated relationship. “Elin really liked Lindsey because the kids really liked her,” said a source close to Nordegren, adding that if Vonn wanted to keep her distance at the party, it would likely be an attempt to avoid any media storm created if there were pictures of them partying together.

But a rep for Vonn insisted that she didn’t ask to be seated away from Nordegren, adding the two women are on “great terms” and spoke at different events over the weekend.
