Caroline Wozniacki celebrated her birthday without her new boyfriend JJ Watt. Is the former world no 1 and the NFL player already going through some couple trouble post Wimbledon 2015?

To celebrate her 25th birthday, Caroline Wozniacki posted a picture from her birthday celebrations on Instagram. It revealed that JJ Watt wasn’t part of her intimate party.

But on the good side - Caroline Wozniacki may be winning her break up war against her ex boyfriend Rory McIlroy. Not only did the former world no 1 shut down a press conference when Rory McIlroy came up during WImbledon 2015, but she also has her new boyfriend JJ Watt’s support to get through it all.

Despite the fact that Caroline Wozniacki fell in the second round of Wimbledon 2015, having JJ Watt by her side might soften her blow.

According to Irish Independent, “A reporter asked her: "Do you have any messages for Rory McIlroy who sustained an injury to his ankle today?" Her response was to bite her lip and ignore the question before glancing at a moderator who promptly said: "We'll stick to tennis questions."”

With that, the press conference quickly ended. Take that, Rory McIlroy!

In fact, Caroline Wozniacki and her boyfriend JJ Watt are stronger than ever! The NFL player and the former world no 1 bonded over her performance at French Open, which means that they will follow suit at this year’s Wimbledon.

According to Us Weekly, “Last month, the two were spotted together in Paris, where the NFL Defensive Player of the Year supported the beautiful tennis pro at the French Open.”

But Caroline Wozniacki may have ditched her boyfriend JJ Watt in preparation for Wimbledon 2015. Instead of filling her Instagram with her boyfriend, the former world no 1 has been uploading lots of inspirational material for her career and her best friend Serena Williams.

And it looks like Rory McIlroy doesn’t make the cut.

She also has been filling her Instagram feed with positive energy. She posted a picture with her best friend Serena Williams, reminiscing the times that they spent in Miami following the massively public breakup with Rory McIlroy.
