Ad exec and former CNBC host Donny Deutsch allegedly skipped out on a nearly $2 million commission earned by Sotheby’s International Realty last year on the sale of his property in Amagansett, LI.

Deutsch made at least a $1 million profit on the deal, Sotheby’s claims in a Manhattan Supreme Court lawsuit.

Deutsch called the lawsuit “frivolous” and “absurd.”
