Tennis pro Caroline Wozniacki is believed to have launched a dig at Rory McIlroy's ex-girlfriend Holly Sweeney by claiming that she "can't move on".
World number one golfer McIlory struck up a relationship with Wozniacki after ending his romance with Sweeney, who appeared on Channel 4's Come Dine With Me cooking reality show with a 'Golf Pros, Tennis Hoes' theme.
Following the programme, Wozniacki tweeted: "It's amazing how some people can't move on from the past and get on with their own lives."
The Northern Irishman has been dating Wozniacki since last year.
