OPINION AND ORDER In this contract dispute over money earned from a couple’s appearances on reality television and subsequent deals with various brands, the latest drama features the couple, their talent manager, and former branding agent. Envy Branding, LLC (“Envy” or “Plaintiff”) is a New York company that identifies opportunities for celebrities to generate revenue from licensing their image or brand. Envy brings this action against The William Gerard Group, LLC (“TWGG”), William G. Dzombak (“Dzombak” and, together with TWGG, the “TWGG Defendants”), Chelsea DeBoer née Houska (“Chelsea”), Cole DeBoer (“Cole” and, together with Chelsea, the “DeBoers”), C&A Enterprises (“C&A”), Dakota Ln LLC (“Dakota Ln”), Down Home DeBoer’s LLC (“DHD”), DeBoer Holding Company LLC (“DeBoer Holding”), and Aubree Says LLC (“Aubree Says” and, together with C&A, Dakota Ln, DHD, and DeBoer Holding, the “DeBoer Companies”). Envy claims that the TWGG Defendants, the DeBoers, and the DeBoer Companies (together, “Defendants”) violated a set of agreements by, among other things, withholding revenue from the DeBoers’ appearances on television and instructing third-party brands not to work with Envy on sponsorship deals for the DeBoers. Envy brings claims under New York common law for breach of contract, tortious interference with contractual and business relationships, and unjust enrichment/quantum meruit. See generally ECF No. 59 (the “First Amended Complaint” or “FAC”). In response, Defendants bring counterclaims for breach of contract under the same agreements, arguing that Envy first breached the agreements by withholding revenue collected from the DeBoers’ branding deals. See generally ECF No. 60 (“Ans.”). The parties have filed cross-motions for summary judgment on all the claims at issue.1 See ECF Nos. 83 (“Pl. Br.”), 98 (“Df. Br.”), 107 (“Df. Opp.”), 119 (“Pl. Opp.”), 121 (“Pl. Reply”), 122 (“Df. Reply”). In connection with its summary-judgment motion, Envy has also moved to preclude the report and testimony of Defendants’ expert witness. ECF No. 82-1 (“Begakis Br.”). For the reasons that follow, the Court GRANTS in part and DENIES in part both motions for summary judgment, as well as Plaintiff’s motion to preclude Defendants’ expert.
