World number one Rory McIlroy found himself discussing Christmas presents instead of his game at a news conference on Thursday when his tennis star girlfriend Caroline Wozniacki demanded a special gift. Wozniacki, 22, put her Northern Ireland boyfriend firmly on the spot as he talked reporters through his first round at the $8 million DP World Tour Championship where he was one shot off the lead. \"You obviously have unbelievable support this week. So, you know if you win this week, am I going to get a really nice Christmas present, and what am I going to get?,\" said Wozniacki, reported the Gulf News. \"Have you not already got a lot of nice presents?\" replied McIlroy. \"I have been looking. But yeah, I don\'t think winning this week will lead to me buying you a nice present. I think you\'ll get a nice present anyway.\" The news conference had reporters in fits of laughter as the two stars stepped up their light-hearted exchange. Wozniacki hit back: \"Well, that must be because I\'m an unbelievable cheerleader.\" \"You\'re a better tennis player,\" joked McIlroy. \"That\'s not nice,\" replied former world number one Wozniacki. McIlroy insisted: \"No, it is. Anything else?\" \"That\'s it for today,\" said Wozniacki.
