Rory McIlroy’s ex-girlfriend Holly Sweeney follows him on Twitter

The real reason for Rory McIlroy’s success lately is not because he’s been practicing more and it’s not because he broke up with Caroline Wozniacki. It’s because Holly Sweeney is back in his life.

Holly is Rory’s childhood sweetheart and girlfriend from his early days on tour. Holly is the one he broke up with to get with Woz.

Since Holly is still a favorite WAG here at LBS (current or former — they all count to us), we still follow her on Twitter. She tweeted Saturday about her baby shower — we told you she was pregnant with her current boyfriend’s baby — and we decided to check what she’s been up to lately.

And guess what? She recently started following Rory again.

Her Twitter activity log shows she began following him between July 27 and Aug. 4.

Look, Holly has a boyfriend — Belfast Giants hockey player Jeff Mason — and is expecting a child, but that doesn’t mean she can’t have some interest in Rory’s life.

Rory, by the way, has been following Holly all along and followed her at the same time he followed Kate Upton. That has to be a sign. And it certainly can’t hurt to have Holly back in his corner.
