Is Serena Williams a sore loser? Maybe. After Sloane Stephens defeated Williams in the quarterfinals of the Australian Open, 20-year-old up-and-coming tennis star believes that Serena not only directed a cryptic "I made you" tweet in her direction, but the younger Williams sister has completely ignored Stephens altogether.

So, in an interview with ESPN The Magazine, Stephens decided to air everything out in the open. Check out what she had to say below:

“She’s not said one word 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 says. “And that should tell everyone something, how she went from saying all these nice things about me to unfollowing me on Twitter.”

Stephens’ mother reportedly tried to stop her from going on, but Stephens continued.

“Like, seriously! 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?”

Maaaaan, tell 'em how you really feel, girl!
