Was Cara Delevingne spotted closely admiring St. Vincent’s engagement ring???

The ongoing saga of whether supermodel Cara Delevingne and girlfriend St. Vincent are engaged to be married continues - and this time Cara has been spotted spying closely on a diamond rock on St. Vincent's hand.

The rock was being worn by St. Vincent on her RIGHT hand following a romantic trip to Paris with her beau - which in some gay and lesbian communities is seen as the new-age way of signifying a monogamous relationship.

And all of this comes just a week after a source told The Sun that Cara was spotted down on one knee with St. Vincent just next to The Eiffel Tower - possibly one of the most romantic spots in the world? Just sayin'.

The source said "I could see Cara on bended knee, clearly proposing to her girlfriend. It was really touching. Cara obviously likes to do things traditionally", but the source later added that she wasn't sure whether Cara was joking with the proposal or not.

So could we be hearing the chime of wedding bells for Cara and St. Vincent soon? It's certainly looking more and more likely as the weeks go by!
