One of the reasons the couple decided to call time on their relationship was thought to be so that Cressida, who is just 25, could concentrate on her career.
She completed a one year contemporary dance course at the Trinity Laban Conservatoire in Greenwich, London, last year.
The pair, who headed off on a skiing trip together to Kazakhstan in March, are said to have been introduced by the Prince's cousin and Cressida's friend Princess Eugenie - although they have moved in the same upper class circles for a number of years.
They began dating around May 2012 - reportedly getting together at The Valley festival on friend Arthur Landon's Hampshire estate.
Prince Harry has split from his girlfriend Cressida Bonas, a source close to the couple confirmed.
The pair, who had been dating for two years, ended their relationship amicably.
"It's very, very sad that they have decided to split. It's very amicable but they have decided to go their separate ways," the source said.
"It is virtually impossible to have a successful romance and relationship in the full glare of the world’s media,” a source told the Telegraph.
Cressida had been widely tipped to marry Harry, with speculation growing in March after she joined the Prince at one of his official engagements for the first time.
Kensington Palace declined to comment.
