Danish tennis star Caroline Wozniacki has denied wedding bells have started chiming for her and world No.1 golfer Rory McIlroy.
Sport's first couple sent tongues wagging on Friday when they arrived in Brisbane with Wozniacki sporting a sparkling new diamond-encrusted ring on her ring finger.
She admitted it was a Christmas present from the Northern Irishman but it wasn't designed to revive continued speculation the pair, who have just bought a Florida mansion together, were engaged.
"It's not an engagement ring," Wozniacki told AAP on Saturday.
"Those rumours once again I'll have to shut down and say we're not engaged ... not yet anyway."
Possessing a quirky sense of humour which saw her in hot water this month for imitating good friend Serena Williams, the former world No.1 denied she wore McIlroy's gift on her left ring finger as a prank.
"I'll wear it on that finger because that's where it fits," said the 22-year-old after waking to headlines of `Is Caroline engaged to Rory?'.
"I just laugh about (the reaction). It's just funny to see. If we're engaged there will be no doubt about it."
Not so funny was the reaction to Wozniacki's light-hearted impersonation of Williams in Brazil this month when she stuffed towels into her shirt and skirt to play a point in an exhibition match.
It brought howls of protest and claims of sexism and racism from the US media until Williams played down the incident.
Wozniacki said she was surprised by the claims and was grateful for Williams' support.
"There was no bad feelings there," she said. "It was just a bit of fun and that's it.
"She's a great girl and a great champion and I only have respect for her."
The world No.10 admitted she'd be more careful in future.
"I'll just think about it a little bit more next time because sometimes people just take themselves a bit too seriously."
One of eight WTA top-10 players at the Brisbane International, Wozniacki starts her Australian Open campaign at Pat Rafter Arena with a first-round match against a qualifier.
But she's drawn to meet top seed Victoria Azarenka in the quarter-finals - which would be the world No.1's second match after receiving a first-up bye.
