*A Jagged Edge fan is disappointed with the band since the group deserted him at the altar.

According to the fan, Victor Diaz, he forked out $10k to have the band perform at his wedding as a surprise for his wife on Nov. 19.

He claimed that he reached an agreement with the band’s reps and gave up the deposit and other costs, but the band never showed up.

But the band is denying even being aware of the booking, telling TMZ that the fan must have been dealing with someone who was pretending to be a representative of the band.

Diaz ain’t with that argument and believes the band flaked on him for a higher paying gig on the same weekend.

So the newly married fan is ready to sue Jagged Edge and the record label as well as the group’s management company.

“They humiliated me and cost my wife her dream,” Diaz told TMZ.

A rep for Jagged Edge says, “They are very heartbroken and sad that [Victor’s] wedding got destroyed due someone using our name without permission.”

The rep adds, “As far as court goes … if the guy does decide to sue, good luck, because we didn’t agree to anything and he will see he had a forgery contract.”
