Skiing star Lindsey Vonn is reportedly pressuring her boyfriend Tiger Woods to marry her. And if the golf superstar declines, Vonn will reportedly split up with Woods soon.

According to the tabloid National Enquirer, Vonn allegedly gave an ultimatum to Woods to marry her, threatening the golf icon that there are other guys who would be more than willing to settle down with her.

"Lindsey told Tiger: If you won't marry me, there are plenty of good-looking guys out there who would," an unidentified source told The National Enquirer.

However, the 38-year-old golfer is allegedly unwilling to tie the knot with the former Olympic skiing champion. The source revealed that Woods has no interest in getting married again.

"He's not interested in getting married again and having more kids," the source said on Woods. "He told her he'd think it over, but secretly Tiger wants out. And if she keeps pushing hard for a commitment, she's playing right into his hands. Marrying Tiger would be complete se­curity for Lindsey. She's worth about $3 million, but Tiger is worth more than 100 times that."

Elin Nordegren Believes Woods-Vonn Relationship Won't Last

Woods' former wife Elin Nordegren has reportedly expressed doubts about the relationship of Woods and Vonn, with sources saying that the Swedish model is convinced that the couple will split up soon.

Nordegren, who received a $110 million divorce payout from Woods when the golfer was caught cheating, reportedly told Vonn not to pressure Woods to marry her. Nordegren said that it could force Woods to break up with Vonn, but the 29-year-old skier did not budge.

"Elin thinks Lindsey is good for Tiger but doubts their relation­ship will last," a Showbiz Spy source said. "She advised Lindsey to not put any pressure on Tiger, but Lindsey went ahead and did the complete opposite. She's demanding a com­mitment, and that just pushes Tiger farther away."

Reports also indicated that Woods told Vonn that they should re-think their relationship when the Olympic downhill champion gave her boyfriend an ultimatum.

"When Lindsey hit him with an ultimatum, it started an argument. Tiger told her, 'If that's the way you feel, we need to rethink this whole relationship," the source added.
