Raheem Sterling has been forced to apologise to world record holder Usain Bolt after a YouTube prank took a lewd turn.
The Manchester City star appeared in a video alongside popular online personality KSI. The pair then sent messages to a number of contacts in each other's phones.
Sterling soon regretted his decision to suggest KSI should message Bolt after the YouTube star asked the sprinter how many women he had slept with.
