Rachel Uchitel’s baby boom

Nightlife vixen and one-time Tiger Woods mistress Rachel Uchitel is leaving clubland behind for her new venture — children’s clothing. Uchitel is opening a baby store on the Upper West Side called Wyatt Lily, named after her 19-month-old daughter with Matt Hahn, who filed for divorce in June. The store will sell reasonably priced baby clothes and goods, including a Wyatt Lily brand. Uchitel was planning to open in January, but threw open the doors early last week after people spotted her setting up the boutique at 290 Columbus Ave. between 73rd and 74th streets. Uchitel was a VIP hostess at clubs including Tao Las Vegas, Griffin and Marquee in New York. But, “being out at night doesn’t work when you have a child,” she told us. “I always wanted something of my own. So I created the business because it was the only way I could be a mom and call into action my love of fashion, New York and my daughter.”
