Olympic skier Lindsey Vonn has described her partner Tiger Woods as an "amazing father" to his two children from a previous relationship.

The former world number one golfer made the headlines for the wrong reasons back in 2009 when it emerged that he had numerous affairs with women during his marriage to now-ex-wife Elin Nordegren.

During his relationship with the Swedish former model, the couple had two children - daughter Sam, seven, and six-year-old son Charlie.

Vonn, who began dating Woods two years ago, has opened up about the golfer's responsibilities as a father.

"They're amazing kids and he's an amazing father," Vonn told People magazine. "You know, I feel privileged to be along for the ride, and I help as much as I can. They're great kids - I love 'em."

Vonn won Olympic gold in the Vancouver Winter Games in 2010.
