NEW YORK (AP) — Ashanti says she was “disgusted” and “absolutely scared” when she learned in July 2013 that a fan who had been convicted of stalking had since been tweeting her X-rated messages and posed for a photo with her sister.

The Grammy-winning R&B singer testified Tuesday at Devar Hurd’s trial. She says she was at a birthday dinner for her mother when another fan pointed out via Twitter that Hurd was the man in a photo with her sister from a 2012 event.

She says she then realized that Hurd was behind Twitter accounts that had sent her explicit, unwanted messages over 100 times in less than a year.

Hurd was convicted in 2009 of stalking and served about two years in jail. He says Ashanti should have blocked the accounts if they upset her.
