Rory McIlroy is a bona fide celebrity now. He and girlfriend Caroline Wozniacki have joined the ranks of Brangelina and Tomkat with their own couples’ nickname - “wozzilroy.”

The 22 year old golfer, who recently won the US Open, coined the nickname himself when he presented girlfriend Wozniacki a golf club that was inscribed with the combination of their two surnames. The nickname was created by the couple themselves instead of short-breathed fans, though it is nonetheless endearing.

The playful exchange was documented on Twitter when Wozniacki tweeted a picture of the club with the message “Here is my new club @McilroyRory made for me'.” The two went on to create a hashtag for the new nickname and tweeted back and forth to each other:

McIlroy tweeted back to Wozniacki, a the world’s top ranked tennis player, “Where’s my racket?!” To which she replied, “'@McIlroyRory your RACQUETS are on the way;) lol.. Yonex are already working on them:) #wozzilroy' .”

Does the new nickname mean there are wedding bells in the near future for Wozzilroy? Doubtful as the two have only been dating for a few months following McIlroy’s split with childhood sweetheart Holly Sweeney. McIlroy has been quoted as saying that Wozniacki has “got a great work ethic and it's something I can probably learn a lot from” of his equally athletic beau.
