The Oscar winner has been dating the French hunk after meeting him on the set of her upcoming film Dark Tide last year (11), and now the pair has prompted speculation they intend to become man and wife.
Berry was spotted enjoying a drink in Malibu, California on New Year's Day (01Jan11) while wearing a huge emerald and gold ring on her engagement finger.
A representative for the star had failed to comment on the rumours as WENN went to press.
Berry has been married twice before - she was wed to baseball player David Justice for three years until they split in 1996, and then to Eric Benet from 2001 to 2003.
The star has one daughter, Nahla, with ex-boyfriend Gabriel Aubry.
