Mother Monster is priming herself for a comeback.

Lady Gaga is "back to work and feeling better," a source confirmed to Us Weekly on Saturday (May 26). “She spent yesterday at Electric Lady Studio in the West Village working on the soundtrack fixes for A Star Is Born and is there today.”

Back in February, the 31-year-old entertainer, who suffers from fibromyalgia, a disease that increases musculoskeletal pain, had been forced to cancel the final 10 European dates of her Joanne world tour. The tough decision was reached five months after the Grammy Award winner broke the news of her tour postponement on Instagram after "suffering from severe pain" that prevented her from performing live at her best.

These days, thankfully, the "Million Reasons" has returned to the studio with her A Star Is Born castmate to put the finishing touches on the soundtrack for the musical drama remake.

“Bradley Cooper joined her at the studio earlier yesterday — they are putting the finishing touches on the music for the movie,” the source added. “Gaga is in amazing spirits and much more back to herself. She has been all smiles and is so happy to be back at work.”

And with the continued support of close friends and medical specialists, the pop star is said to be feeling like herself again; she even hit up a West Village bar in NYC with a few old pals earlier this week. The insider continued, “She couldn’t have been more down-to-earth, smoking cigarettes on the street and having a blast. It seems like the old Gaga is back.”

Gaga will star alongside Cooper in A Star Is Born on October 5.
