Did Bradley Cooper Give Irina Shayk This Royal-Worthy Engagement Ring?

First comes love, than comes baby carriage, then comes marriage — maybe

Bradley Cooper and Irina Shayk are already planning for the arrival of their bundle of joy, but it looks like they could be planning their wedding, too.

On December 15, Shayk was photographed in Los Angeles rocking a sizable gem on her ring finger, People reports. Any stand-alone jewel on that finger is enough to give a spectator pause, but this one in particular screams wedding bells: It bears a striking resemblance to Princess Diana's engagement ring, which Prince William proposed to Kate Middleton with in 2010.

The only difference between the royal rock and Shayk's ring? Hers is an emerald, while Middleton's is a sapphire.

People notes that neither Cooper nor Shayk's camps have commented on the potential engagement, but if that is, in fact, an engagement ring, double congrats to the expecting and surely elated couple.
