Model-actress Kelly Brook hasn't confirmed an engagement just yet, but she didn't hide a huge diamond ring on her wedding finger in a new selfie.

The "Piranha 3D" actress, who was busy partying here with her French boyfriend Jeremy Parisi, shared a make-up free selfie on her Instagram page on Friday, reports mirror.co.uk.

Pulling the covers up over her face as she lazed in bed, the 36-year-old flaunted the ring in the photograph.

The image comes after speculation that Brook is set to marry her beau.

The couple, who started dating last year, enjoyed a romantic festive period in France with Parisi's family.
