America's World No. 2 golfer Dustin Johnson has broken his silence about rumours of a break-up with fiancee Paulina Gretzky, daughter of ice hockey great Wayne. Paulina recently deleted all pictures she had with him on Instagram, indicating that they could be heading for a split.

According to a report in British tabloid, The Sun, Johnson's proximity with socialite Yassie Safai was the reason for his relationship woes. On Tuesday, Safai denied reports of a relationship with the golfer.
