Rihanna narrowly avoids a nip slip in plunging jacket

Rihanna went out for dinner in a jacket that looked like her Nan’s cardigan on Saturday night. But unlike Nana Ri Ri, the sexy star decided not to bother with a blouse or any trousers.

Rocking the plunge wool cardigan look is tough at the best of times but the Diamonds singer managed to make it work with dangerously high denim cut offs and a few buckets of baby oil.
