The 22-year-old student – who dumped Harry last month because she was fed up with his constant partying and lack of commitment – arrived at the prince’s London home, Clarence House, in the early hours of Saturday morning (01.12.07), following a night of partying.

A royal source told the News of the World: “Harry was very keen to spend some time with Chelsy before she flies back to South Africa for the holidays. He knew he was in the wrong when it came to the break-up so he is doing all he can to get back into her good books.

“This was the last realistic opportunity of them seeing each other.

“They have been in touch by phone and text but they both made no secret of how much they were looking forward to seeing each other just to catch up.”

This was the first time Harry, 23, and the Zimbabwean-born student had met since Chelsy ended their three-year relationship three weeks ago. The couple had met earlier in the evening at the Chelsea home of Chelsy’s friend Olivia ‘Bubble’ Perry.

At 7.30pm they went out with friends to 24 nightclub in the West End, but left separately after two of Chelsy’s friends had a row. Chelsy was dropped off at Clarence House 10 minutes after leaving the club.

Royal sources refused to comment on whether the young couple will get back together for good.

The insider said: “Chelsy is planning on spending some time catching up with her pals in South Africa before joining her brother and other family members in Kenya over Christmas.

“There’s still an outside chance Harry and Chelsy will spend New Year together at Bazaruto, a luxury island of Mozambique, but that will depend on Harry’s army duties over the festive period.”

Meanwhile, army officer Harry has finally kicked quit smoking.

A source told the Sunday Mirror: “It’s still early days and he has failed before, but this time he’s determined. He feels he is finally winning the battle. Harry used to feel really guilty. And Charles is so pleased that he seems serious about quitting for good this time.”

The prince – who vowed to quit in January – started smoking aged 14 and continued his 20-a-day habit throughout his army training.
