Did Tweet Sideline Caroline Wozniacki And Rory McIlroy's Relationship?

Sports' golden couple, tennis star Caroline Wozniacki and golf ace Rory McIlroy reportedly may be breaking up over a tweet. INSIDE EDITION has the details.

Has a golf superstar dumped his gorgeous girlfriend because she released an embarrassing picture of him?

Golden couple, Rory McIlroy and tennis ace Caroline Wozniacki have been dating for two years and they seemed inseparable. But last month, Caroline posted a photo of Rory fast asleep with his mouth open on Twitter with the caption: "JETLAG! LOL!"

Her friends were stunned.

“Omg Caro u are soooo mean!!!!,” tweeted Serena Williams.

Another friend tweeted, “I suspect someone will not be too happy with you Caroline.”

Now, a well-regarded newspaper in Ireland where McIlroy lives, is quoting a source as saying, "Yes they are over. It's a difficult time for them both."

The golfer was asked about the rumored break-up at a golf tournament in South Korea, but was tight lipped.

He said, “My private life is private and I’d like to leave it that way.”

Caroline is insisting the relationship is not over. She was quoted as saying, "All is well and there's not much more to say about it."

She is a well-known prankster spoofing pals like Serena Williams on the tennis court. But this time, did she go too far or is her boyfriend seriously lacking a sense of humor?
