The 19-year-old starlet, who was wearing a tight fitting dress at the concert, leaned over during one part of the performance and seemed to expose part of her left nipple.
But, not one to let a little nip slip get her down, Lovato continued on with the concert, and didn't even address the incident via Twitter.
Following the show, Lovato tweeted: "Dallas was on fire last night! New Orleans here we go!"
Way to have a show-must-go-on mentality.
