The Northern Irish golfer, 25, and Danish tennis star, 23, have chosen a location abroad for their wedding, which will be attended by 200 family members, friends, and other celebrities from the worlds of sports, politics and entertainment.
A source divulged “They've only been engaged a few months, but they're both keen to make it official and are a planning a spectacular day for guests. They're keeping their invite list under wraps for now for security reasons because it includes some A-list superstars from around the world.”
In a recent interview, Wozniacki said she was eager to start a family.
“I want to be a relatively young mother, and I do not see it as being too far in the future.
“Therefore I have no dream to make my mark. Instead, I enjoy economic freedom my hard work has given me.
“It means I can give my children the best start in life by being there 100 percent for them.”
Currently number 14 in the world rankings, Wozniacki has earned over $15million from tennis.
McIlroy, formerly number one and currently ranked 10th in the world, has earned over $30 million.
