Cheeky courtside DJ trolls Dimitrov with break-up song

Grigor Dimitrov suffered a stunning capitulation at the Stuttgart Open after the stadium DJ played the one song he didn't want to hear.

The 25-year-old Bulgarian is the ex-boyfriend of former Pussycat Dolls lead singer Nicole Scherzinger.

He was leading Juan Martin del Potro 4-3 in the first set of their clash on Wednesday when the DJ played one of Scherzinger's biggest hits 'Don't Cha' during a change of ends.
