Mary-Kate Olsen's
still wearing a giant ring on that finger!

The former "Full House" star showed off her massive engagement(?) ring while out with her 44-year-old beau Olivier Sarkozy at a book launch party in New York on Tuesday. 

Sporting a slicked-back 'do, a long black pea coat paired with a white furry clutch, the Olsen twin looked happy as she posed for photos with her much older love.

The blonde beauty was also still rocking her giant gold sparkler on her ring finger, which leads us to believe that the the pricey piece really is her engagement rock.

The couple have yet to confirm if they're actually headed down the aisle, but Mary-Kate hasn't taken off her gold accessory since she first debuted the ring last month.

Well, the couple does look happy together -- what do you think about her gold bling? Tell toofab in the comment section below and check out even more PDA-filled pictures of the twosome above!
