On Monday, actress Alyssa Milano confronted an online impostor who was pretending to be her on Twitter.com.

The former child star — who has over 400,000 followers on her well-trafficked social networking site –confronted a person holding a fake account who was posting messages under an ID similar to her the name of her Official Blog.

“Maybe Alyssa Milano would like to tell us all why she is pretending to be me,” Milano wrote. The imposter’s account has since been suspended. A brief message on the fake’s page now reads: “Sorry, the profile you were trying to view has been suspended due to strange activity.”
