If allegations are proven true, Tiger Woods may have had extra marital affairs with at least two women, Rachel Uchitel, 34 and Jamie Grubbs, 24, according to media reports.

Tiger Woods' alleged mistress Uchitel has denied to several media outlets she had any involvement with the player after the National Enquirer reported she began dating Woods in June.

But Grubbs publically claimed that she dated the golf champion for more than two years starting in April 2007.

The Grubbs story is expected to be published on the printed version of US Weekly magazine on Wednesday.

The golf player is married to supermodel Elin Nordegrin.
