Cheryl Cole ignores 'jealous' Hough?

Cheryl Cole has shown Derek Hough the cold shoulder, according to a report.

The Sunday Mirror understands that the dancer was showing signs of jealousy due to Cole's relationship with Black Eyed Peas frontman will.i.am.

"The pair were in each other's pockets non-stop and she even gave him the lead role in her video for the single 'Parachutes'," a source claimed.

"But now it seems the friendship has cooled off big time. Derek's green with jealousy after seeing snaps of Will and Cheryl together.

"He sent Cheryl a text trying to act chilled asking what was going on but she just ignored that message and sent one back saying, 'Hope all is well x'," the insider added.
