The couple was the subject of reports last week (beg08Feb16) after the supermodel-turned-actress was spotted down on one knee allegedly proposing to her musician girlfriend in front of the Eiffel Tower in Paris, France.

The rumours were neither confirmed or denied at the time. However the loved-up pair was spotted at an airport in France on Friday (19Feb16) with St. Vincent - real name Annie Clark - wearing a sparkling diamond ring.

Cara, who is set to star in the upcoming movie Suicide Squad, is then seen closely examining the ring on her girlfriend's hand by pulling it up close to her eye, as if measuring carat size.

The ring was seen on Annie's right hand, which is considered in some gay and lesbian communities as a way or marking a monogamous relationship.

The couple, who were first spotted together at the Brit Awards in February last year (15), are believed to have been dating since December 2014.
