Yesterday, the 'Tonight (I'm Lovin' You)' singer's representatives confirmed that Iglesias will not be appearing on the 26-date tour to support Spears's latest album Femme Fatale.
Iglesias addressed fans via his WhoSay page to apologise for the cancellation, soon after Spears had announced his involvement in the tour on Good Morning America.
"Hey guys, sorry for the confusion regarding a possible tour in the summer with Britney Spears," Iglesias said.
"We are on the 'Euphoria Tour' and will continue to do so including some soon-to-be-announced dates in US. So hope to see all of you soon."
