Mary-Kate and Ashley Olsen are back!

It was years ago since they were last on screen together - when they were 18 years old! Now, they will be performing for a monthly collection of videos called the "T monthly", where they will be promoting T-shirts.

In the videos, Mary-Kate and Ashley are tending to a barbecue whilst showing off the new T-shirts from StyleMint. There will be 8 T-Shirts a month to try, each costing $29.99 each for StyleMint members.

The video is meant to be full of laughs and great fun - exactly what StyleMint wish the T-shirts to be. The video is obviously causing quite a stir as it has been a while since the sisters have been in the limelight, and has thrown up rumours such as when they plan to make another TV series together, or maybe they might go into presenting jobs. We will have to wait and see. To watch the video, go here.
