Andy Murray and his girlfriend Kim Sears have "mutually agreed" to end their relationship after four years together, his representative has confirmed.
Kim, 22, who was seen cheering Andy on at tennis matches around the world, is said to have moved out of the £5million Surrey mansion the couple shared and returned to her parents' home.
A friend of the pair said: "No one else is involved. Both Andy and Kim are saddened that the relationship is over, but they mutually felt it was time for them to part."
"They are both very young and it is not unusual for young people to split up."
Another pal of the British number one – also 22 - added: "There were no blazing rows or anything like that. Kim left Andy's house under amicable circumstances.
"They are still in contact with one another and remain good friends."
Kim is the daughter of Britain's Fed Cup captain, and head coach of women's tennis, Nigel Sears.
She is about to complete a degree in English Literature at Sussex University in Brighton and intends to pursue a career in publishing.
