Should J.J. Watt's girlfriend Caroline Wozniacki be worried? Watt and Wozniacki have been mum about their brewing relationship though they've been spotted together on several occasions. Plus, there seems to be one woman who can tame NFL's 26-year-old defensive beast and she's none other than "F.R.I.E.N.D.S" actress Jennifer Aniston!

It appears that even NFL players aren't immune in getting starstrucked when they meet Hollywood celebrities especially meeting their celebrity crushes. And proof to that was J.J. Watt's encounter with 46-year-old actress Jennifer Aniston, where the huge Texan player "blacked out the entire time," Yahoo! News reported.

"It was incredible," Watt told Us Weekly. "She was so sweet. She was awesome. Everybody has kind of known for a long time that she was the one person that I've wanted to meet... And she was really sweet and awesome and I'm thankful that she was so cool because I was not."

Even though Watt got a chance of a lifetime in meeting longtime celebrity crush Aniston at their talent agency this week, he admitted that there are some things he would have done differently.

"If I went back - if there was like a tape of it and I could watch it again, there are many things that I would do differently," he confessed. "But no, I shook her hand and we had a conversation, so I don't think that I completely botched it. But she was very sweet and I had a good time."

After the chance encounter, J.J. Watt shared a photo of him with Aniston on Twitter, with a hashtag #LifeMade.

Though J.J. Watt, who said he doesn't have a girlfriend, revealed that his dream of meeting Jennifer Aniston has been dead for a while, he admitted that making his lifelong goal a reality was indeed incredible.

Meanwhile, love is definitely in the air between J.J. Watt and rumored girlfriend Caroline Wozniacki. New York Post revealed the NFL hunk has been linked to the 25-year-old blonde tennis stunner because they have been spotted hanging out on several occasions: at the NCAA Championship game in April, at the French Open in May and on a weekend getaway in Florida.

In April, J.J. Watt and rumored girlfriend Caroline Wozniacki sparked romance speculations after they were seen together in the Wisconsin Badgers game. According to USA Today's For The Win, the rumored couple was cheering on the Badgers as they snapped Kentucky's undefeated season.

Recently, NFL's "Defensive Player of the Year" J.J. Watt and alleged girlfriend tennis superstar Caroline Wozniacki were spotted together in Fisher Island, Florida. Does this mean that Wozniacki has found love in Watt after ex-beau Rory McIlroy unceremoniously ditched her?
