“The people who are assigned to helping stars walk the red carpet were being aggressive and Kelly was trying to ignore it,” an insider told The Mail.

“By the time she got to the last woman she had had it because she scolded Kelly and told her to move when she was trying to wave to fans and help the paparazzi get their shot,” they added.

The source also revealed: “[Kelly] doesn’t care if she comes across like a diva.”

The incident comes months after Kelly walked off the set of the Today show because she was dissatisfied with her dressing room. Sources say Kelly’s dressing room, which was larger, was given to Jennifer Lopez.

Kelly was upset by the closet-sized dressing room she was left with.

“Kelly spent her entire career in Beyonce’s shadow and she’s tired of the disrespect,” a source told Sandrarose.com.

The source said Kelly is checking everyone who disrespects her.
