Lady Gaga and her on-again, off-again boyfriend Michael Polanski were spotted attending U2 and Katy Perry concerts in Las Vegas.

Lady Gaga was spotted with her boyfriend Michael Polanski at a pair of concerts over the weekend, and also saw Katy Perry and U2 respectively at their Las Vegas residency shows.

The 37-year-old actress and singer was photographed with Polanski, the 45-year-old tech mogul, as well as her manager Bobby Campbell at Perry’s Resorts World Residence in Las Vegas PLAY on Friday.

A fan captured video of the trio moving around the show, which runs until November 4.

The Poker Face singer and Polanski were subsequently seen at The Sphere at the U2 concert on Saturday as they were photographed at the show’s VIP concert, where the band’s lead singer Bono mentioned she was in attendance.

“I better sing these notes right, Lady Gaga is in the house tonight,” the rock icon said from the stage, according to the Las Vegas Review-Journal.

At the last show, the famous couple looked at ease: In an image posted on TwitterThe Edge of Glory artist was pictured wearing a blue and brown flannel shirt with her blonde locks tied back.

The singer, whose real name is Stefani Germanotta, wrapped up her own Lady Gaga Jazz & Piano residency at Park MGM on Thursday.

Polanski was photographed inside the state-of-the-art establishment wearing a dark blue sweatshirt and gray cap.

Other notable names at the U2 show included Eddie Vedder, George Clooney, Brad Pitt and Tom Brady, according to the newspaper.

The Born This Way singer and tech investor were spotted out and about in Sin City last month, fueling reconciliation rumors after they called it quits after a three-year relationship earlier this year.

The couple reportedly ended their union amicably and remained friends. In August, they were seen together for the first time in more than a year.

The couple first became romantically involved on New Year’s Eve 2019 and later became Instagram official in early 2020.

Polanski graduated from Harvard University in 2006 and runs Napster founder Sean Parker’s Parker Group.

Over the years, Gaga and Polanski attended the Super Bowl, BAFTA and Critics Choice Awards together.

They reportedly decided to go their separate ways due to the fact that the singer-songwriter wanted to get married and have children, and the technical director was not ready to take those steps.

The relationship “hit a wall” and simply ran its course, OK magazine reported in March of this year.
