The Red Queen has a deal.

Louise T. Blouin, who owns BlouinArtinfo, Art + Auction and Modern Painters, has finally sold off her 4,551-square-foot West Village penthouse apartment.

She pocketed $23.7 million for the spacious pad, according to spokesperson Melanie A. Bonvicino.

Anne Prosser of Halstead-Douglas Elliman, represented Blouin in the sale, which once had an asking price as high as $40 million before being marked down to $35 million in 2014 and then $29.95 million at the end of 2016.

Over the years, Blouin also listed the four-bedroom, four-bath duplex — with an 1,800-square-foot wraparound terrace and spectacular views of the Hudson — as a $60,000-a-month rental.

Martha Stewart and Christie Brinkley were once neighbors.

Blouin still has a compound on tony Gin Lane in Southampton but is said to be spending most of her time in Europe.
