Rory McIlroy, 24, and Caroline Wozniacki, 23, are engaged.
McIlroy posted the following photo to his Twitter account on Tuesday.
A spokesman for McIlroy told AP that he proposed in Sydney, where Wozniacki is preparing for the Australian Open.
The duo have been dating since 2011. She was seen following him as recently as November, where she was on-site at the DP World Tour Championship in Dubai.
But it hasn't always been smooth sailing and syrupy serenades. Amid McIlroy's struggles on the golf course in 2013, the couple was the subject of much scrutiny. There were even rumors of a Wozzilroy split at numerous points throughout the year, the most recent in October.
But with his lone win of the year coming late in the season at the Australian Open, and this most recent development in his personal life, it's safe to assume bigger and brighter things are in store for McIlroy in 2014.
