Is it love-all for Redfoo and Azarenka?

Could there be something brewing between World No.1 tennis player Victoria Azarenka and LMFAO frontman Redfoo?

That's the impression tennis fans got on Monday when the 23-year-old started her Australian Open campaign in Melbourne.

Rumours abound that the afro-haired muso has been following Azarenka's tennis journey for months, but the pair raised eyebrows when Redfoo was spotted in the crowd signalling and making faces at the Belarusian player - who responded in the same manner - after she claimed victory on the court.

The 37-year-old DJ/rapper remained tight-lipped when asked by the Seven Network if there was anything going on between the two.

"I don't like to kiss and tell," he said.

"But we are really close, and she's a very special person and I'm very happy in my life right now."

Meanwhile, the attention continues to centre on Bernard Tomic's new love – former Miss Croatia, Gold Coast beauty contestant Chelsey Grbcic.

Since making her debut as Tomic's new love at the Hopman Cup in Perth, the pretty blonde has continued to show her support, having snagged a seat in Tomic's player's box while watching the Aussies claim victory on Tuesday night.
