Kelly Brook posts Playboy test shots wearing just pearls on Instagram

English model Kelly Brooks posted a series of snaps on her Instagram profile, wearing nothing apart from a string of pearls.

The 33-year old former girlfriend of Danny Cipriani posted some sizzling photos, which were taken as a Playboy test shoot back in 2010, where she is seen lying naked on a beach and another one where she is seen sipping herbal tea wearing just a towel with palm trees, sunshine, and a pool in the background, the Daily Star reported.

The brunette model's nude test shoot didn't make it to the US magazine, but she was seen wearing a white collar and bow tie in the September 2010 edition.
