The pair spark rumours that they're back together

It seems that Prince Harry and Chelsy Davy could be an item again after partying together at Princess Eugenie‘s surprise 22nd birthday bash on Friday night.

The couple’s on-off relationship ended after 5 years in 2009 but Chelsy, 26, is still friendly with 27-year-old Harry and remains part of his social circle.

Prince Harry was there and so was Chelsy. Clearly they are still close,’ reveals a royal source.

‘They appeared at ease with each other and were chatting happily together.

‘Whether or not they have rekindled their relationship is anyone’s guess but they certainly seemed very friendly.’

During his recent tour of South America and the Caribbean, Harry reportedly wore a ‘love pendant’ given to him by Chelsy while they were dating.

‘Harry is still hung up on Chelsy. He sees her as the one who got away,’ a pal tells the Daily Star.

Harry‘s brought out the necklace Chelsy gave him years ago and he wore it practially every day on his recent trip to the Caribbean and Brazil.’

But Zimbabwean-born Chelsy, who attended the Royal Wedding last year, is said to be unsure about whether she wants a partner who is as famous as her ex.

Harry and Chelsy split very amicably and have always remained friends,’ an insider tells The Sunday Express.

‘There have been times since they broke up that they have been more than that. They’ve never stopped loving each other but being together is difficult with Harry‘s military career and the publicity any relationship attracts.

Chelsy is very fond of Harry but she doesn’t want to live her life in the limelight.’
