Bad cook Jessica Biel

Bad cook Jessica Biel

Jessica Biel made her dog sick when she tried to cook for boyfriend Justin Timberlake.

The 'I Now Pronounce You Chuck and Larry' star - who has been dating 'SexyBack' singer Justin since last January - reportedly attempted to make him a romantic meal, but Justin couldn't stomach her food.

A source said: "Jessica made Justin this really disgusting meal. He didn't like it, so when she went out to run some errands he tried to slip the remaining food to Jessica's Pit Bull Terrier Tina. But as soon as Tina had eaten it, she threw up!

"When Jessica got back, she asked Justin what he thought of the food and he told her it was delicious. But he finally confessed and she found the congealed food in a pile by Tina's water bowl."

It was recently reported Justin is planning to propose to Jessica, and his grandmother Sadie is already planning the ceremony, insisting the pair should marry Jessica in Justin's mother Lynne's backyard.
