(CNN) For someone who says she is usually asleep by 10 p.m., Simona Halep pushed past her bedtime during tennis' off-season.

The Romanian threw a private bash for 110 family and friends at a Bucharest restaurant in celebration of her long-awaited, maiden grand slam title at the French Open in June and partied until the small hours. "I celebrated until 5 a.m. actually for the first time in my life," Halep told CNN by phone ahead of the Australian Open. Her time away from the tennis court wasn't restricted, either, to that one evening in the Romanian capital, where the world No. 1 has an apartment. "I spent a lot of time in the city, which I don't do very often," Halep said. "I lived a normal life, which I enjoyed a lot. I met new people, stayed with friends."

No wonder, then, that Halep didn't sound as confident as 12 months ago entering the Australian Open, which starts Monday. She is still waiting for a first win since August after being downed 6-4 6-4 by Ashleigh Barty in her 2019 opener in Sydney Wednesday. And in the first round at the Australian Open, Halep faces the player who beat her in the first round at the US Open, Kaia Kanepi. "I have no expectations, so I come different to last year, but still I'm motivated to give my best every time I step on the court and believe I have a chance to do a good result, but we will see," said Halep, speaking before her outing against Barty. "It's really tough to talk about this long period I had to rest." READ: Nadal -- next generation ready READ: Meet tennis' unluckiest loser Boris Becker? It was during her three-and-a-half year partnership with Cahill that Halep said she hoped the highly respected Australian -- a former coach of Hall of Famer Andre Agassi and Lleyton Hewitt -- would be in her corner until retirement. They remain friends and Halep said he gave her advice in the off-season. With Cahill continuing to work as an analyst for ESPN television at the Australian Open, who knows, he might give Halep more pointers. For the most part, she intends on flying solo at least until the clay-court swing in April. "I need a coach. But for the moment I just say that I want to take the responsibility to see how it is going to be, the next three, four months," said Halep.

The Constanta native denied reports, though, that one of them was Novak Djokovic's former coach, Boris Becker. "He came for a different reason in Bucharest and I was happy to see him, but we never talked about being together as a coach and player," said Halep. When Halep refers to a "tough, emotional year," the exit to Kanepi and her sojourn to the Australian Open final figure to be in the equation, too. Homecoming crowds Halep needed to be hospitalized after suffering from dehydration in the gripping Australian Open final in which she led Caroline Wozniacki by a break deep in the third set before losing 2-1. Even before then, the Romanian rolled her ankle in the first round and featured in marathon encounters against Lauren Davis in the third round and Angelique Kerber in the semifinals, when a combined five match points were saved en route to victory. Her path to the French Open final was simpler, a mere one-set surrendered. JUST WATCHED Roger Federer: My dream opponent would be... Replay More Videos ... MUST WATCH
