Then he sent a flunky to hire DVDs from his local Blockbusters store, so the pair could curl up in front of the telly together.
The day-long date was the first time law graduate Chelsy, 23, has been in Harry's pad at Clarence House since she dumped him in January for flirting with other girls.
It is the clearest signal yet that their five-year romance is back on.
A close source said: "They were just hanging out together like any other couple does on a Sunday - chilling out on the sofa watching DVDs.
"They're just testing the water right now. But neither of them have anybody else and they're very happy to see each other." Friends say the pair plan a holiday together in South Africa as soon as they get a break from their busy schedules.
Harry, 24, and Chelsy fuelled rumours of a reunion when they were spotted flirting and partying together at central London club Raffles last Saturday night.
He was reported to have returned to Clarence House alone and she was said to have gone to her London home. But a few hours later Chelsy was snuggled up in his flat - and did not leave until 7.30pm on Sunday. She was given a police escort by royal protection officers.
Harry left minutes later for a helicopter course in Shropshire.
Dad Prince Charles and wife Camilla were in Scotland. Clarence House officials do not comment on Harry's private life. But our source said: "He and Chelsy are very comfortable together."

I guess I'm as guilty as anyone, because I love to keep up with what the royals are doing, but I just hope people give these brothers some room and cut them some slack. It is not my place to say who they should or shouldn't love. After a very difficult chilhood and the incredible pressure of life as a royal, I just hope they find happiness.

when is he going to put a ring on her finger??? they have been together on and off for like 5 years. that is long enough time to figure out if someone is right for you or not. Besides, they arent young anymore, they're out of school and career cant be THAT important. Nowadays, you can have both marriage and career. I just dont understand whats stopping them from getting married. They're rich, successful, they have place to live, they have jobs and they obviously love each other.. what are they waiting for???

I prefer Chelsy over Kate at least she is doing something else other than waiting for the ring.

Liz I'm with you on this one. The girl has no standing or upbring to be associated with a royal.
God save the Queen.

It's nice to know that they're spending time together quietly. Harry and Chelsy are far more mature than William and Kate. It's nice to know that Chelsy seems to care about Harry because of the person that he is, not the title that he has. Unlike Kate who is willing to tolerate anything to get the tiara, Chelsy has self respect and a work ethic.
Chelsy seems to be made of the 'right stuff' regardless of how much money her family has. She's willing to work to make her way in the world and push herself forward. Good luck to them both!

Why was Chelsy Davy given a 'Police Escort' when she left Clarence House? as well as 'Royal Protection Officers'? I didn't realise our budget for their safety stretched to their on/off girlfriends as well?

These two are such a likeable couple, unlike his brother and his missus

Kate is lazy. She stands around looking at everybody's shoes.

Both of them should do what they like - just like the rest of us - Only dont make us pay for it
By laura.. Posted September 20 2009 at 6:35 PM.
Yeah 'watching DVDs'. That's what I used to call it too.

VERY well said J Thompson. You have voiced what lots of people think. Harry and Wills have both chosen the wrong girls.

Reading the following comments it's made me realise I much prefer them as a couple than Prince William and his toff girlfriend...who has apparently got qualifications and does buggar all with them!!
Chelsey seems to be hard working and getting on with her studies and wow!! Actually work for a living...Kate Middleton...what are you doing??
So I reckon if their getting back together they seem really nice and suited. I think it's hard being associated with any 'famous' person let alone a royal.
If they can make their relationship work, then I think good for them!! Congratulations!
P.S. and you know its nice seeing them do normal things and not going out purposefully to garner attention in the media and getting drunk!

Meant to add that I've met both of them at the Concert for Diana and they make a great couple and are really lovely.

I like Harry but it would seem he is damned whatever he does, leave him alone he is a young man who lost his mum at very very young age trying to find his way in life. And they are like most young couples who enjoy spending time together and want to see if their relationship has a future but unlike most young couples it is done in the public eye so who can blame them for wanting to spend an evening alone indoors it's what couples do isn't it.....

j thomoson your a disgrace,the girl is 23 leave them be ,what harm are they doing to you?your "common" remark stinks of prejudice.what a plonker you really are.

Oh no, not Princess Chav! Isn't it enough that we all ready have Fergie lurking around?!
By Liz.. Posted September 20 2009 at 11:05 AM.
The thought of a Princess Chelsy makes me shudder. I don't care for her fathers associations and I don't particularly care for Chelsy. She is common.
