Eva Longoria Parker gave online fans a saucy shock after joining Twitter.com - she accidentally directed her followers to a porn site.

The Desperate Housewives star signed up to the micro-blogging website last week, but it took her a while to get to grips with the technology.

When the actress tried to direct her fans to her husband, basketball star Tony Parker's Twitter address, she accidentally sent them a link to an X-rated website.

After realizing her mistake, she quickly urged fans to stay away from the sexy site: "Oh noooo! I put the wrong Twitter site for my husband!! The one I put earlier goes to some porn site!!!! Don't use it!"
