Sloane Stephens is serving up criticism of one-time idol Serena Williams in an upcoming ESPN The Magazine feature. In the May 13th issue, Stephens blasts Williams as going out of her way to be unkind to her and insists their relationship only started to deteriorate after she beat Williams at the Australian Open last January.

“She’s not said one world to me, not spoken to me, not said hi, not looked my way, not been in the same room with me since I played her in Australia,”Stephens told the magazine. “And that should tell everyone something, how she went from saying all these nice things about me to unfollowing me on Twitter.”

Stephens wasn’t finished there; as her mother reportedly tried to slow her down, she added: “People should know. They think she’s so friendly and she’s so this and she’s so that--- no, that’s not reality. You don’t unfollow someone on Twitter, delete them off of Blackberry Messenger. I mean, what for? Why?”

Stephens also responded to a cryptic tweet that Williams sent two days after their quarterfinal match in which she simply said: “I made you.” “I was like, You really don’t know that that’s about me? “Stephens told the writer, adding that all the rumors about Williams once serving as a mentor and being her favorite player are just that.

“I’ve always said Kim Clijsters is my favorite player, so it’s kind of weird,” she said. Stephens concludes by reflecting on an episode in which she claims both Serena and older sister Venus branded her with a bad impression of the both of them. “I waited all day for an autograph,” she said of an instance when she was just 12 and first say the sisters play in Florida. “They walked by three times and never signed our posters.”
