It cannot be an easy time for Caroline Wozniacki, she's been through a horrible few months after fiance Rory Mcllroy ended their relationship after sending out the wedding invites.
What must be even worse to take, however, is seeing the incredible success that her ex is having with a club in his hand. The Northern Irishman has been in a rich vein of form since ending their association.
Understandably the very public nature of their relationship meant that questions and general furore was inevitable after their separation.
Woznaicki has had to deal with it throughout Grand Slams at Wimbledon and the French Open. Journalists were even banned from mentioning the golfer's name when asking the Dane questions during the tournament.
The 24-year-old is keen to be known for her on-court heroics rather than off-court drama, starting with the US Open, and has sought to clear up any lingering talking points involving her private life.
"I don't want to have my name stuck with him forever," she told the New York Times. "I'm my own person. I have my own career."
The world no.11 struggled on-court in the immediate aftermath; she bowed out in round one of the French Open, and, despite some better performances, couldn't pass the fourth round stage at Wimbledon a month later.
Indeed Wozniacki did admit that the whole situation came as a shock: “When it comes out of the blue,” she continued, “that’s like a shock. It’s like someone dies right in front of you.”
The former world no.1, aside from a few digs on Twitter, hasn't exactly vented her frustrations at McIlroy. In fact, she has been trying to avoid spending too much time focusing on her former partner's progress: "I don't follow his life and I don't really follow golf anymore."
The Danish star will now hope that everything is tied up and she can focus on going one step further than she did five years ago in New York.
Her loss in the final against experienced star Kim Clijsters remains her best attempt at a Grand Slam. Consecutive semi-final appearances followed after that but her record at Flushing Meadows has come off the boil with third and first round losses.
However, this year, as tenth seed, Wozniacki will be among the favourites to challenge in the later rounds.
Her campaign will begin against world no.56 Magdaléna Rybáriková but soon enough she'll be hoping to focus on some of the top stars in contention - there are plenty of them after all.
Serena Williams, as always, will be the favourite as defending champion and world no.1, the local favourite will hope to bag Grand Slam no.18. However the winners of the summer majors - Maria Sharapova and Petra Kvitova - will look to continue their own good form.
