Christina and Matthew met on the set of the 2010 movie, Burlesque. According to People, the pair began dating shortly after the singer filed for divorce from Jordan Bratman. “Matthew is a special person. We had a really strong friendship on the movie," Christina told People. "He’s the kind of person you could spend hours on the phone talking to and all of a sudden it’s daylight.”

Matthew previously worked as a production assistant in Los Angeles, but he now serves as an executive for MasterClass, according to Variety. Matthew was an early partner with the coaching company, investing in MasterClass through his investment firm, MX — which he shares with Christina. He also serves as the senior VP of talent and business development for MasterClass and has played a key role in expanding the company’s roster of industry experts.
