Flirty Prince Harry reportedly took a shine to model Danielle Lloyd at the Diana Memorial concert after party � much to girlfriend Chelsy�s disgust.

The former WAG�s ample cleavage caught the eye of Harry and his chums, according to an eyewitness.

�Harry couldn�t take his eyes off her boobs,� says the source. �She�s a very tall girl in her high heels and when he chatted to her he kept talking to her cleavage.

Chelsy apparently put an end to the flirt-off by storming over with a �face like thunder,� causing Harry to slink back to his girl�s side like a naughty school boy.

Sounds like she�s got that one under the thumb!
