One Direction's Zayn Malik and Little Mix singer Perrie Edwards have been an item for a while now, and it's serious enough that he's even had her face tattooed on his arm. But a ring she was recently sporting has some people thinking the couple has decided to make things permanent.

The Little Mix bandmates turned out to support 1D for Tuesday's London premiere of the movie 'One Direction: This Is Us,' where Zayn and Perrie held hands and smooched on the red carpet and later sat together to watch the film.

But what celebrity-watchers were buzzing about was the fact that Perrie had something especially sparkly on the ring finger of her left hand -- a bauble that wasn't there at the Teen Choice Awards a little more than a week ago. So are the 20-year-old singers newly engaged?

No official word yet, but take a look at a close-up of the ring below and decide for yourself.
