(dailymail.co.uk) - She found the pressures of being the long-distance girlfriend of a partying prince too much to bear.
But it seems Chelsy Davy may have succumbed once more to the charms of Prince Harry.
She stayed the night with him at Clarence House after being dropped off there in the early hours of Saturday.
Chelsy, 22, who is studying at Leeds University, broke up with Harry a month ago after complaining about his endless partying and lack of commitment to their three year relationship.
But she spent last Friday night downing shots, hitting the dancefloor and cavorting with nearly naked barmen
The 21-year-old student partied at a trendy London nightclub until the early hours of yesterday morning with the barmen, provided by a waitering service called Butlers in the Buff.
When she finally left at 3.10am she climbed into a waiting car with her friend Olivia Perry, nicknamed Bubble, began texting furiously - and a few minutes later was being driven through the gates of Clarence House.
The late-night antics prompted fresh speculation that she may be getting back together with Prince Harry.
Chelsy, who is studying at Leeds University, had reserved two VIP tables at the newly refurbished 24 nightclub in the West End on Friday.
She arrived shortly after midnight with Bubble and the pair wasted no time in heading for the bar.
An eyewitness at the Fantazia night said: "As soon as the pair walked into the club they headed straight over and ordered vodka and cranberries and a sambuca shot each.
"They then went over to join friends on two VIP tables that were being guarded by their very own bouncer.
"Chelsy seemed to be in heavy conversation with a guy called Will Kenyon, a party organiser for The Dorchester, for some of the evening.
"He couldn't take his eyes off her all night but Chelsy was more interested in chatting with her friends and hitting the dancefloor."
The blonde, who is planning to return to South Africa for a family Christmas next week, appeared to be having a lot of fun.
However, the smoking ban caused a few headaches for Chelsy - she had regularly to leave the dancefloor, make her way into a private courtyard and hide behind a green bin to have a crafty cigarette.
An onlooker said: "Chelsy and Bubble would leave via a fire escape and a doorman would hide them behind a green bin so they were able to have a smoke without being seen.
"They would return to the club shortly afterwards and they did this three times during the whole evening."
There were nearly naked barmen from Butlers in the Buff everywhere, serving drinks and posing for pictures with clubbers during the so-called "society rave".
"The male models were walking around the venue with only aprons to hide their modesty and their naked behinds were visible for all to see," said one onlooker.
Butlers in the Buff is a model/stripper waiting service that promises to spice up any event it attends.
The organisation's website says: "You need to serve your guests right? Why not make that service unforgettable."
"Chelsy was keen to get on to the dancefloor with the butlers and she and her female friends ended up dancing in between the semi-clad men and semi-naked female dancers on platforms," the onlooker said.
"The happy house music was really getting Chelsy in the mood to dance and she didn't seem to mind that she was mingling with the near-naked people."
Chelsy has been studying hard for her master's degree at Leeds over recent weeks.
Last week she was spotted making last-minute corrections to an important essay in the communal computer rooms and is regularly seen walking around the university campus with friends.
"Chelsy wanted a big night out as she has been working so hard at university," said a witness.
"She was glued to her friend Bubble's side all night - they even went into a lavatory cubicle together."
Chelsy, dressed in a revealing black dress, was attracting a great deal of attention from the males in the VIP area.
"There were a lot of men who were vying for Chelsy's attention," the onlooker said.
"She was certainly the subject of their affection, although she did not seem interested in any of her suitors - she was definitely set for a girls' night out."
Just before she left, Chelsy became particularly perturbed when a Prince Harry doppelganger became fixated with her while she waited near the bar.
"Chelsy got really fed up with the guy who was standing next to her," an eyewitness said.
"He was the spitting image of Harry and just stood behind her boring his eyes into the back of her head.
"Although she seemed quite put off by the attentions of the Harry double, Chelsy seemed quite cheeky to any other admirers that approached her."
When Chelsy eventually left the club, she had a heated exchange of words with Bubble.
"The girls were discussing how they could leave the club without being trailed," the onlooker said.
"Chelsy did not want to leave via the front exit, though her friend seemed convinced it was a good idea.
"Eventually they decided to hide back in the courtyard for 20 minutes, behind the green bin, before rushing to a car waiting by the front door."
The pair left at around 3.10am and headed over to Clarence House, where they disappeared through the gates at about 3.30am.
A Royal spokesman said: "We don't comment on Prince Harry's private life and we would never comment on Chelsy Davy."
