Christian was spotted spending time with Gaga earlier in the year, as she warmed up for her Half Time Show at the 2017 Super Bowl.
Christian also attended the Interscope's Grammy After Party with Gaga earlier this year, where he spent time playing the dutiful boyfriend as she mingled with fellow celebs.
This is Lady Gaga's first relationship since she called time on her engagement to Chicago Fire star Taylor Kinney. The pair, who became engaged on Valentine's Day in 2015, broke up last year much to our dismay. However, the singer appears to have recovered just fine from her split.
Wishing Gaga and her new man all the best as they continue enjoying their Summer in the Hamptons.
