Prince Harry is famous for his cheeky charm, but it seems his charisma was too much for his lingerie model girlfriend, who reportedly dumped him because he couldn't stop flirting with other women.
The third in line to the British throne raised royal eyebrows when he started dating Florence Brudenell-Bruce in June.
The new couple were planning their first holiday together when they split suddenly earlier this month.
Royal sources initially said Harry had ended the romance because he didn't want to be "tied down", but Florence has reportedly told friends she called time on the relationship because the party prince was constantly chatting up other women.
"She felt he had a wandering eye all the time and she wasn't really into not knowing who he was flirting with or talking to when they were apart," an unnamed friend of Florence's told the UK's Sunday Mirror.
"So she ended it. She didn't want to carry on in a relationship that wasn't going to go anywhere.
"Call it a summer fling. They both enjoyed themselves but Flee wasn't interested in taking things further."
Florence is the first girl Harry has dated since he split from Chelsy Davy in May.
Chelsy and Harry have been dating on and off for several years but she is believed to have ended the romance for good because she doesn't want to marry into the royal family.
Your say: Do you think Harry will get married one day, or remain a royal bachelor?
