“Today” show contributor Jill Martin has purchased a home in Southampton, says the listing agent for the firm that marketed the property.

Martin, who is also a broadcaster for the New York Knicks and has co-authored fashion guides including “I Have Nothing to Wear!” and “Fashion for Dummies,” recently closed on the property for $3.7 million, says Thomas Cavallo of Douglas Elliman Real Estate.

The shingled, newly constructed home by Cavallo Building has six bedrooms and 5 1⁄2-bathrooms. It features a dining room with coffered ceilings and a master suite with a fireplace. The great room has a large fireplace, built-in cabinets and French doors that open to a stone patio. The lower level has a home theater room, sauna, wine cellar and exercise room.

The nearly 0.4-acre property has a heated gunite saltwater pool and separate pool house.

“What made the house so attractive for this buyer is the luxury custom construction and details,” Cavallo says.

Martin could not be reached for comment.
