Jessica Alba posted a sexy photo of herself on Instagram earlier this week. The image features the gorgeous actress flashing a lot of leg in a red hot dress while gazing at the camera with a sultry stare.

The 32-year-old mother of two wrote: "Played dress up 2day."

She should play dress up every day!

After the photo shoot the actress ditched the dress for jeans and a t-shirt but kept the dark make-up on.

So how does she stay in shape?  She told E! News that she was working out "diligently" but she doesn't have time to do that anymore while she's busy taking daughter Honor to school and just being a mom.

In April, she shared a somewhat scary weight-loss trick with her fans. She told Net-a-Porter: "It was brutal; it's not for everyone. I wore a double corset day and night for three months. It was sweaty, but worth it."

Alba stars in the upcoming film "Machete Kills."
