Scoop - Jessica Alba cooks! And even when she's at home in her kitchen, sans make-up and chopping up veges, she still manages to look super cute.

Hubby Cash Warren posted a photo of his actress wife - who joined Twitter only a few weeks ago, and already has 28,000 followers - as she was preparing their dinner.

"Just got hm from work...wifey @jessicaalba cooking up a storm, yum - like she doesn't already have enough on her plate," he wrote.

Jess earlier revealed that she's been under the weather, tweeting "Just got our Xmas tree. Feeling festive despite my cold :)".

So, despite the fact that she was cooking a roast in a hot kitchen, she was tightly rugged up!

"It's freakin 40 degrees in LA," Cash tweeted. "I know it's a lot colder elsewhere but come on, this is LA. Can't decide if I like it or hate it."
