Irina Shayk pregnant and engaged to Bradley Cooper? And is the model's huge emerald sparkler similar to Kate Middleton's ring?

Did Bradley Cooper and girlfriend Irina Shayk give another surprise to their fans? Barely two weeks after her pregnancy news, Shayk was spotted with a huge emerald sparkler.

This week, Shayk flashed a huge emerald sparkler on her ring finger that sparked the rumours that her boyfriend and actor Cooper has popped the question. The 30-year-old supermodel was leaving a spa in Los Angeles when she flashed the huge emerald gemstone encircled by diamonds on her left hand. Shayk, who is reportedly in her second trimester, covered her baby bump in a black printed dress, but she was not able to hide her engagement ring.

Shayk's emerald ring is non-traditional, but it reminds us of the most talked about engagement ring of the Duchess of the Cambridge, Kate Middleton, which was an heirloom sapphire. The ring also looks similar to Lindsay Lohan's $300,000 worth engagement ring.

Shayk and Cooper are dating since spring last year and recently it was revealed that the model is expecting her first child with the actor. Reports suggest that Shayk is due sometime in May. "Irina is feeling wonderful. She is so happy. Bradley and her can't wait for their baby to arrive in the summer. They [also] know the sex of the baby," E! News quoted a source as saying.

"Bradley's mother [Gloria Campano] and Irina are very close, and she has been really supportive. She is ecstatic to be a grandma. She is a really kindhearted mom. They get along great—even when Bradley is working they hang out," the insider said, adding, "Irina and Bradley are mainly staying at Bradley's house in California when they are not travelling. They both have apartments in New York City, but always stay together."
