Cannon has allegedly wasted no time in letting the celebrity mother-of-four that he's definitely got his eye on her.

"Nick hits on Heidi every chance he gets," an insider tells Life & Style Magazine this week. "He's always telling her she's gorgeous and what a great mom and businesswoman she is."

And apparently Klum is loving the attention too, even though she's been dating art collector Vito Schnabel for over a year now.

"[Heidi] eats it all up. She can't stop herself from flirting either," the mag reports.

Meanwhile, despite being one of the most beautiful women in the world, earlier this year Klum admitted that she thinks she is "too curvy" to be considered a high fashion model. The Germany's Next Top Model hosts apparently thinks she isn't in the same cateogry as other runway models such as Naomi Campbell, Kate Moss and Gisele Bundchen.

"I was never a catwalk model," Klum told the Sydney Morning Herald.

She added, "I never really fit in the clothes. I was always too curvy, I was always a lingerie model, even when I was still in Germany when I won my modeling contest I would do lingerie and swimsuits because I was always too curvy for high fashion."
