The former Manhattan nightclub executive — who was the first woman linked to philandering golfer Tiger Woods — welcomed her first child with husband Matt Hahn at 5:04 PM PDT on Tuesday.
“Both Rachel and baby are resting comfortably,” her spokesperson confirmed.
According to Matt’s Facebook, the little girl’s name is Wyatt Lilly.
Hahn, a former football player at Penn State and now a businessman in San Fransisco, married 37-year-old Uchitel in October last year.
Of the pregnancy and marriage, Uchitel has said: “We are really happy and feel extremely fortunate to have one another.”
She was previously engaged to an investment banker who was killed in 2001 during the September 11 attacks on the World Trade Center.
The former Celebrity Rehab with Dr Drew patient was the first of Woods’ mistresses to be revealed, but before that, was linked to Bones’ David Boreanaz.
