Haack launched her champagne line Clé Cachée in September 2025 and told PEOPLE that a Napa trip with Larocca helped turn her obsession into a business idea. She says she picked Grand Cru grapes, set sugar content and traveled to Reims and Épernay during development, calling this the first product she managed from conception to execution beyond her Christina & Kylie design work.
Haack has been dating Larocca since fall 2024. He commented on the post, "What an amazing trip!! Thank you for planning literally everything!!! Love you," and she replied, "Love you baby." Larocca has also appeared in promotional material for her champagne, including a December photoshoot.
