Lindsey Vonn is scared Tiger Woods may cheat with his ex-wife Elin Nordegren and recently demanded he bring her along for a summer trip to Sweden the golfer and his ex-wife were planning to accompany their two young children.

According to The National Enquirer, Woods has been planning the trip for some time now, but as his targeted travel date grew closer Vonn demanded she be included in the traveling party.

“Elin found out what Tiger was planning and told him he can come to Sweden, but not bring Lindsey,” a source told The Enquirer.

The magazine added the 28-year-old Olympic skiing champ is convinced Woods, 37, still has feelings for his ex and “if he got the chance” would dump her in a flash to get back together with Nordegren.

Vonn and Woods begin dating several months ago and earlier this fall took their relationship public by attending several high-profile New York City charity events together.

Despite recent reports Nordegren considered Vonn to be “a good influence” on her ex, the source told The Enquirer the thought of the two being alone together in an exotic land seem to spook Vonn to no end.

“It started a huge fight between the women, with Elin saying she doesn’t want Lindsey around her kids,” the magazine reported, adding that Vonn is convinced Nordegren still wants to control the world’s top-ranked golfer.

Woods and Nordegren, 33, were divorced in 2010 after reports of his numerous extra-marital affairs became public.
