She claimed that the singer is envious of her looks and stormed off at the red carpet event because the press were more interested in her and husband Peter Andre.
The glamour model told OK! magazine: "Pete said he saw Jamelia laughing at me when I was on the red carpet posing for pictures. But then they [the photographers] started all calling my name and she stormed off in a huff!
"Jamelia, don't be angry with me because you've been battered with the ugly stick."
However, according to a report in the Daily Mirror, it was Jordan that got frustrated by Jamelia.
A source commented: "When she saw snappers crowding around the singer, she moaned, 'Why are you taking photographs of her when you could be photographing me?'"
