One of the acts announced for this summer’s celebration of the nation’s 250th anniversary has left plenty of people scratching their heads.

Freedom 250, the organization created by President Donald Trump to spearhead the anniversary events, announced on Wednesday that this summer’s “Great American State Fair” on the National Mall would feature Martina McBride, Vanilla Ice and C+C Music Factory as well as Morris Day & The Time, who later announced they would not be performing.

But one name on the list caused a bit of confusion: Milli Vanilli, the European duo best known for not singing their songs.

The group was initially composed of Fab Morvan and Rob Pilatus, the latter of whom died in 1998. Morvan has been performing the music solo on stage in recent years, with live vocals usually accompanied by a DJ.

Their Grammy Award was revoked ― the first and only time that’s ever happened ― and consumers who purchased the music were offered refunds.

The news release announcing their selection didn’t mention that history. It simply stated that Milli Vanilli was the “internationally recognized act known for chart-toppers including ‘Girl You Know It’s True.’”

Morvan hasn’t commented on the gig, and Jodie Rocco ― one of the musicians who performed on Milli Vanilli’s albums ― told The Associated Press on Thursday that she hadn’t been approached about the concert.

Critics on social media were baffled by the selection:
