Caroline Wozniacki continued her news conference shenanigans at the Australian Open yesterday, telling a tale of being scratched by a kangaroo and then later admitting on social networking website Twitter she had concocted the whole thing.

After making the quarterfinals with a 6-3, 6-4 victory over Latvia's Anastasija Sevastova, the Danish world No. 1 told reporters she was attacked by a baby kangaroo at a wildlife park outside of Melbourne and had needed to get medical attention.

"I thought I was going to be nice and try to help it out because it was just lying there. I thought maybe it needed some help... I found out that I shouldn't do that," said Wozniacki, after pointing to some tape covering a 'wound' on her leg.

"Yeah, it scratched me pretty well.

"I went to the doctor. They cleaned it and everything. They wanted to do a few stitches. I said, 'there's no way you're going to do stitches'.

"It looked so cute. But once it started scratching me, I was a coward and I ran away."

Wozniacki said on Twitter: "Round 2 with the media:) hope you enjoyed my kangaroo story, hope you know i was just kidding:) see you on tuesday for round 3!"

She later returned to the interview to apologize to the media.

"I'm sorry if I've caused any harm or made your job a little bit more difficult," she said. "But the kangaroo story, I made it up because it sounded better than what actually happened. I walked into the treadmill."

The Dane ran her own media conference earlier this week after being fed up listening to questions about her status as a world No. 1 without a grand slam title.
