Tiger Woods and Lindsey Vonn confirmed their relationship earlier this week and the big question on everyone's mind was: how can one of America's sweethearts date someone with his relationship past?

According to sources, the Olympic skier and the golfer have discussed his former infidelities at length. 'He has explained his side and owned up to what he did wrong,' a source told People. 'He has been honest with her.' A pal of Vonn's insists she's 'not freaked out by his past' and is trusting her instincts about Woods, who she was friendly with before they began dating a few months ago.

'She's very comfortable with the relationship,' the pal added.

Another source of reassurance was Woods' reaction to her sidelining crash at the Alpine World Championship in February. He flew her from Austria to her home in Vail, Colorado, on his private jet. Woods 'has been really supportive as she recovers from her injuries,' the pal said.

Despite confirming their relationship publicly, the couple will be tight-lipped about their union in the future. 'I don’t plan on addressing this further as I would like to keep that part of my life between us, my family and close friends,” the 28-year-old champion skier wrote on Facebook.

Woods added on his page: 'We want to continue our relationship, privately, as an ordinary couple,' .
