Rory McIlroy - battling to win his first US Masters in Augusta - is making his tennis star girlfriend Caroline Wozniacki quite the nervous wreck.
Wozniacki, 21, chatted with British tennis player Laura Robson on Twitter as McIlroy, 22, went into the third round just one shot off the lead.
"Check out Rory getting the fistpump out on the 18th! Love it!!" the Daily Express quoted Robson as tweeting.
Wozniacki responded to her comments saying, "I know!! Important hold!! Getting heart attacks here."
McIlroy, from Northern Ireland, told reporters in Augusta, Georgia how he felt about his girlfriend's enthusiasm.
"It's great that she understands how I feel when I play," he said. (ANI)
