I bet he's already cheating on Lindsey Vonn, says Tiger Woods' ex-mistress

Washington, Mar. 21 : Tiger Woods' former mistress has warned his new girlfriend Lindsey Vonn that he might already be cheating on her as the ski champ does not look his type.

According to the Herald Sun, the former hooker/porn star Devon James -the 16th woman to come forward in the Woods' sex scandal in 2009 - said that she was shocked when she saw images of the couple on Facebook.

James told TMZ.com that she thought that the golfing legend would have picked a woman who was more petite and not someone who was more muscular and had a bigger head than his.

She said that maybe Woods' taste changed since Elin Nordegren and the 27 mistresses.

"But you know when the pics came out of Woods and his new girlfriend ... somewhere, 15 other girls were going , 'Huh? I thought I was his GF!'" she added.
