Just days before the first date of her second Bud Light-sponsored Dive Bar Tour, Lady Gaga has postponed it.

A statement from the singer and Bud Light issued on July 11 reads:

“Unfortunately Lady Gaga needs to postpone the first stop of the 2017 Bud Light Dive Bar Tour this week in Las Vegas. She’s deep in rehearsals for her world tour and is working to reschedule a new date as soon as possible. She can’t wait to see all of you soon.”

The tour was scheduled to begin Thursday in Las Vegas at a venue to be announced shortly before the performance.

The reason for the postponement was unclear at press time.

A report in the Las Vegas Review Journal Monday cited sources speculating that the date might move, or might move to another venue than the unannounced original one. Variety also published an earlier report that the date was expected to change.

It is unclear whether the delay will affect the additional dive-bar dates — scheduled for July 26 in Los Angeles and August 30 in New Orleans — and Gaga’s long-anticipated 60-date “Joanne” world tour, which is set to launch August 1 in Vancouver. The singer’s critically lauded halftime appearance at the 2017 Super Bowl , as well as her headlining slot at April’s Coachella festival, have built anticipation for the tour.

The singer premiered a new song called “The Cure” at the festival, which was released officially shortly afterward. Gaga has teased that more new music is on the way, although whether it will be released as a new album or (more likely) an expanded version of “Joanne,” which came out in October 2016, is unclear.

In 2016, Gaga went on a three-city tour with the brand to promote the release of her newest album “Joanne.” In a press release announcing the 2017 installment, Gaga said: “How could I not want to go back to bars and sing music from ‘Joanne‘? I’m excited to re-team with Bud Light for the Dive Bar Tour this summer.”

Plans call for two additional artists to join the tour, with performances live streamed on Bud Light’s Facebook page.
