Melbourne, Jan 14 : She's been moping around Sydney looking miserable and scarily thin - such is the fate of model Irish-Indian Siobhan Parekh, who just broke-up with tennis star Mark Philippoussis.

The couple have gone their separate ways after an 11-month relationship and Parekh is reported to have taken the split quite badly.

Parekh was spotted looking far from her bubbly self.

"She has lost so much weight - she was small before but is now minuscule," the Daily Telegraph quoted a source, as telling Confidential.

"She is such a very sweet, sweet girl and I would hate to think (Mark) has done the wrong thing by her," the source added.

The reason for the split is unknown. (ANI)
