The woman who sparked golfer Tiger Woods' infidelity scandal is pregnant with her first child.
 
Rachel Uchitel married boyfriend Matt Hahn in Las Vegas less than a month ago, and the couple is already planning parenthood.
 
Life & Style magazine reports Uchitel discovered she was going to be a mom while she and Hahn were going through the audition process to become a contestant couple on globe-trotting reality TV show "The Amazing Race."
 
A source says, "She found out she was pregnant when she auditioned for 'The Amazing Race.' They were going to try out to be a couple on the show, and when she had a drug test, it came back positive that she's pregnant."
 
Uchitel became a household name after her fling with Woods was exposed in November 2009.

On Wednesday the Celebrity Rehab contestant confirmed the news by posting a couple of pictures to her Twitter page with the messages "@MattyHahn checking out my baby bump at 5 months..." and "Expecting big things for 2012... Five down, Four months to go..."

Uchitel tells Us Weekly, "We are really happy and feel extremely fortunate to have one another."
