Tiger Woods' former mistress Rachel Uchitel welcomed a baby girl Tuesday night, her rep confirms. It is the first child for the 36-year-old and her husband Matt Hahn, who wed last October following the brunette bombshell's stint on Celebrity Rehab with Dr. Drew.

Uchitel, who lost her fiance Andy O'Grady in the September 11 attacks on the World Trade Center, was thrust into the public eye when news broke that she was one of the many women involved in the Tiger Woods cheating scandal.

After making a name for herself as a VIP hostess and nightclub manager, the new mom is now in the process of getting her forensic investigation license.

We wonder if the golf great sent over a congratulatory baby gift?!
