London, Feb 11 - Australian pop star-turned-actress Sophie Monk has split from her plastic surgeon boyfriend.

Monk, 30, and Dr John Diaz started dating last year.

Monk insists the split was amicable, reports The Daily Star.

She tells Sydney radio station 2DayFM, "He is a lovely guy and we're still really good friends so there is nothing crazy about the split.

"Sometimes it just doesn't work out - especially with me." (ANI)
