The sprint champion has left the gorgeous fashion designer Slovak so that she wouldn’t “distract” him from training.
The split follows a race row in Bolt’s homeland of Jamaica, wherein he drew intense criticism from his female fans for choosing a white partner.
Earlier this week sources close to both Bolt, 25, and Slovakian-born Slovak insisted that they were very much in love.
But on Thursday night a Jamaican news website reported that the pair had agreed to end their relationship.
“It was a mutual decision between two adults,” the Sun quoted a source as telling the website.
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.
The Jamaican superstar track hero hopes to smash his own records and retain his titles at the London Games this summer.
Lubica, 28, had immigrated to Canada when she was 14 and studied fashion design in Toronto.
She moved to Jamaica after falling in love with it on holiday and was introduced to Bolt last year through a mutual friend, reggae singer Tami Chynn.
They were said to be “very comfortable together” and to favour quiet dinners over glitzy functions.
But they received a barrage of abuse after a picture of them kissing was published last month.
“He will have plenty of time for relationships. At the moment he’s concentrating on his running career and doesn’t want anything to distract from that,” a source close to Bolt said.
