Lady Gaga Dedicates Jazz & Piano Residency Show in Las Vegas to Boyfriend Michael Polansky: 'My Mister'

The Grammy winner shouted out her boyfriend of more than four years during one of her final Jazz & Piano concerts at Park MGM's Dolby Live

Lady Gaga is feeling sentimental as her Jazz & Piano residency in Las Vegas comes to a close.

During the second-to-last show of the years-long residency at Park MGM’s Dolby Live on July 5, the Grammy-winning superstar dedicated the show to Michael Polansky, her boyfriend of more than four years.

Gaga, 38, referred to Polansky as "my mister" while making the dedication in the midst of the concert, and then she gave a shoutout to her longtime manager, Bobby Campbell, who recently got engaged to lawyer Robert García.

Last month, some fans speculated that Gaga and Polansky could be expecting their first child after photos of the A Star Is Born performer attending her sister Natali Germanotta's wedding in Maine surfaced online. However, she was quick to shut down the rumors.

Gaga shared a close-up of her bleached eyebrows in a video on TikTok with a cheeky reference to Taylor Swift's song "Down Bad," writing in onscreen text, "Not pregnant -- just down bad cryin at the gym." She also used the moment to encourage fans to register to vote in the upcoming U.S. election.

Engagement rumors also surrounded Gaga and Polansky's relationship earlier this year, after she was spotted with what appeared to be a large diamond ring on her left ring finger during an April outing. A rep for the singer did not respond to PEOPLE's request for comment at the time.

Upon the release of the "Rain on Me" musician's latest HBO concert special, Gaga Chromatica Ball, in May, she opened up about plans to release new music during a Q&A at the film's Los Angeles premiere.

"I am in the studio every single day. I have written so many songs, I've been producing so many songs, and it's nothing like anything that I've ever made before," Gaga, who teased "LG7" at the end of the film, said at the event.

"I love to break genre, and I love to explore music," she continued at the time.
