Before Sunday’s Grammy Awards, Madonna wanted to get in a few last minute workouts and surprised patrons by attending not one but two public spin classes in LA!

A source at Cycle House in Los Angeles tells us that “heads turned” when Madonna walked in with her 17-year-old daughter Lourdes on Friday, Jan. 24th.

The two participated in one of the gym’s famous spin classes, which the iconic singer liked so much that she returned the following day for a second workout!

“Madonna came in just before class wearing black track pants, a black top, black beanie, and sunglasses,” the source says. She also appeared to be wearing a gold grill in her mouth!

“[She] wore black riding gloves to complete the look and chose 2 lb. weights for the arms section of class,” the source adds.

The workout consisted of a 45 minute full-body ride and a cool-down stretch afterwards.

And just because she attended a public class doesn’t mean the superstar didn’t go incognito.

“Before leaving, she made sure to put her vest, sunglasses, and beanie back on,“ the source shares.

Madonna is no stranger to public workouts. She’s been spotted taking part in a few near her home on New York’s Upper East Side!

We can’t wait to see what the star will wear on the Grammy red carpet tonight! Do you think the 55-year-old will show a lot of skin? Sound off in the comments!
