MARY-KATE OLSEN - MARY-KATE BUYS HER OWN ENGAGEMENT RING

MARY-KATE OLSEN won't be taking any chances on her boyfriend's taste when she decides to wed - she has already bought her engagement ring.

The Olsen twin has reportedly bought herself a $250,000 (GBP138,900) vintage ring - even though she hasn't even got a regular date.

The 19-year-old actress, who is still broken hearted after splitting up with Greek shipping heir STAVROS NIARCHOS in October (05), bought the antique 19th century rose-cut diamond-and-emerald engagement ring from a private broker, according to American magazine In Touch.

A pal tells the publication, "Mary-Kate hasn't worn the ring yet. She keeps it tucked away in her jewellery box, but she takes it out to show her friends and she looks at it all the time, too. It's breathtaking."
