While it is unknown what caused the dispute, Daily Mail has contacted Rowland’s representative for comment.
Rowland’s heated moment on the Cannes steps comes just a few weeks after she stormed out of the Today Show.
While speculation has spiralled regarding her reason for walking out, one of the rumours suggests that Rowland was dissatisfied with her dressing room, thus forcing Rita Ora to step in at the last minute.
However, insiders allege that Rowland stormed off the show due to the “disrespect” shown to her by Today Show co-host Savannah Guthrie, who “aggressively” asked the singer about Beyonce instead of basing her questions around Rowland’s latest film, Mea Culpa, which she had appeared on the talk show to promote.
The dressing room rumour appeared to be confirmed by fellow Today Show co-host Hoda Kotb, who offered to share her dressing room with Rowland the next time she came on the show.
But Kotb’s comments seemingly made things worse, as a source told The Wrap that Rowland left after she “felt disrespected’ following Guthrie’s bombardment of questions about her former bandmate.
“Kelly was offended that Savannah repeatedly and aggressively asked her about Beyonce” the source told the publication.
The insider went on to say that the dressing room speculation was far from the truth, saying: “The story was spun that Kelly didn’t like her dressing room, but she has been on the Today Show numerous times, she and her team know the dressing room set up.
“That would not come as a surprise at all.”
