News of the split follows a race row in his homeland after the 25-year-old was criticised for going out with a white woman but the relationship was defended by friends close to Bolt who described the couple as being very much in love.
They were said to be 'very comfortable together' and to favour quiet dinners over showbiz functions.
But they received a barrage of abuse after a picture of them kissing was published last month.
The split follows a race row in Bolt’s homeland of Jamaica, where female fans caused an outcry by criticising him for choosing a white partner. Earlier this week sources close to both Bolt, 25, and Slovakian-born Lubica insisted they were very much in love.
But last night a Jamaican news website reported the pair had agreed to end their relationship.
A source said: “It was a mutual decision between two adults.”Bolt, the reigning Olympic champion and world record holder over 100m and 200m, is famed for his lightning speed along the track and post-victory pose.
