Caroline Wozniacki appeared to take a dig at her ex-fiancé Rory McIlroy as she watched him win the Masters at Augusta.
The former world No 1 tennis star pointedly threw her support behind another player prior to the tournament.
In an interview with ESPN, Wozniacki said: "We pick one that we think has a big chance of winning, and that was Ludvig Aberg."
Despite her prediction, McIlroy held his nerve on a tense final round to defeat Justin Rose in a sudden death playoff.

Aberg, Wozniacki's pick, finished seventh in the prestigious tournament.
Wozniacki and McIlroy were once considered a sporting super-couple, dating between 2011 and 2013.
Their relationship ended abruptly when McIlroy called off their engagement in a three-minute phone call.
The shock breakup came just days after they had sent out wedding invitations following his New Year's Eve proposal in Sydney.
Wozniacki later revealed her devastation at the manner of their split.
"I was shocked. I thought at least I would get a face-to-face or something, but there was nothing," she told Graham Bensinger.

"It was a phone call, and I did not hear from him again. It kind of just ended."
McIlroy began dating his now-wife Erica Stoll just months after ending things with Wozniacki.
The couple married in 2017 and have a four-year-old daughter, Poppy.
Their relationship hit the headlines last year when McIlroy filed for divorce in a move that appeared to come out of the blue.

There were rumours of a potential romance with CBS sports journalist Amanda Balionis after they appeared to enjoy a strong rapport during an interview.
However, the divorce petition was voluntarily dismissed weeks later.
McIlroy said last summer: "Over the past weeks, Erica and I have realized that our best future was as a family together."
Stoll was a loyal supporter at Augusta, positioned by the 18th hole as McIlroy secured his victory.
The golfer went straight to his wife and daughter after winning, pulling Stoll into an embrace.
