Could it be that Bradley Cooper and Suki Waterhouse have followed Cheryl Cole's lead and gotten wed in secret?

The couple, who have been together for 18 months, have sparked speculation after the British actress went out wearing an eye-catching gold ring.

We couldn't help but notice that the model was wearing the new piece of jewelry as she was seen shopping along Magazine Street in New Orleans.

Is this the new Mrs Bradley Cooper?

Not only that but the gold accessory was on just the right finger to imply that she might have said 'I do' to her hunky fella.

Dressed in a grey hoodie and a short black skirt, the possible-newlywed headed to vintage clothes stores before getting herself a manicure.

Later that day she popped to see the Hangover star on the set of his new film Adam Jones.

For a while now there's been rumours that the twosome were engaged but the stars have managed to keep any plans to get hitched on the down low.

However, now it looks like the duo may have already walked down the aisle without letting us know.

Perhaps the pair were impressed by Cheryl Cole who managed to keep her nuptials under wraps when she married Jean-Bernard Fernandez-Versini earlier this month.

While the X Factor judge received a lot of criticism for her hasty ceremony, most of this was because the couple had been together for such a short time.

It's not likely that Brad and Suki would get the same reception as they've been together for a year and half.

In that time they've also managed to cement themselves as one of Hollywood's cutest couples by stepping out together on many occasions.
