Lady Gaga has one hardcore piece of advice — or is it shade? — for Sunday’s Super Bowl 2020 halftime headliners, Jennifer Lopez and Shakira.

The Grammy and Oscar winner minced no words while mentioning the much-hyped duo during her pre-Super Bowl concert Saturday at Miami’s Meridian at Island Gardens venue.

“I better hear no lip-syncing tomorrow!” the 2017 halftime show star bellowed from her glitzy keyboard at the AT&T Super Saturday Night Show. “Put your drinks up! I love you, Miami! I love you, J.Lo! I love you, Shakira!”

Not all of the Twitterverse was lined up behind Mother Monster, who previously beefed with pop icon and 2012 halftime headliner Madonna.

“She’s pressed she didn’t get the half time performance,” one catty commenter posted, apparently missing the fact that the 33-year-old artist, born Stefani Germanotta, has already been there, done that. Another sniped, “As if she doesn’t also lip sync.”

The native New Yorker frequently referenced her own Super Bowl showcase — beginning with a dramatic entrance while suspended from wires — throughout her two-hour set Saturday.

“Thank you so much for believing in me,” Gaga told her adoring, cheering fans. “I remember when I played the halftime show and it was one of the most special, beautiful things that’s ever happened to me. So, thank you.”

The concert was a breather from her ass-out hookup with Harvard-educated entrepreneur/investor Michael Polansky.

By the end of her corporate gig, Gaga walked back her halftime vocal coaching, saying, “I wish so much love and so much luck to everyone that’s doing the halftime show, [and] to both the teams that are playing each other in the Super Bowl. They’re all champions.”

Page Six exclusively reported Saturday that Lopez, 50, and Shakira, 43, will be joined onstage by reggaeton superstars J Balvin and Bad Bunny — with an assist from Lopez’s 11-year-old daughter, Emme.
