Kyrgios and Azarenka's love match?

Valentine's Day is still a couple of weeks away but could we already have a budding romance at the Australian Open?

Well if Twitter is anything to go by, we just might.

Aussie ace *Nick Kyrgios *and *Victoria Azarenka *flirted up a storm at the weekend after the Belarusian chimed in on Kyrgios' Twitter feed, where he was conducting a quick Q&A with fans.

After some standard questions, the 25-year-old former women's world No. 1 got in on the action, asking him: "How can I learn to serve as big as you?"

Kyrgios, 19, answered: "Private lessons of course!" To which Azarenka replied: "Okay I'll book one."

The pair's first public flirt came on Twitter back in September when rumours swirled of a potential mixed-doubles partnership.

Azarenka, below, previously dated musician and X Factor judge *Redfoo * but dumped him last year.

Meanwhile, Kyrgios, above, recently said he was single and would only consider a relationship with someone who understood what tennis meant to him.

"Being a professional and striving to be the best is a tough journey so they'd have to be understanding of not only the time it takes out but also the mental dedication," he said.
