Bradley Cooper and Suki Waterhouse Soon to Marry?

Bradley Cooper and girlfriend Suki Waterhouse might soon be taking the next step in their relationship.

US weekly exclusively reported that the model is itching for an engagement ring.

"Suki says she's been warming him up to the idea of marriage and he's starting to get excited about it," the source tells Us. "It's up to Bradley to pop the question, of course, but she hopes it happens soon."

The American Sniper actor, 40, and Waterhouse, 23, began dating in March 2013, and made their first Hollywood appearance together at the star's American Hustle NYC premiere that December. Cooper was previously married to actress Jennifer Esposito from December 2006 to November 2007.

Waterhouse also has babies on the brain and likes the idea of having kids in the future.

She added of Cooper: "Look, maybe it's best for me to say, 'I'm not one of those girls who goes on about their boyfriends.' I do think whatever I say will sound weird. But the truth is, if I start talking about him, I probably won't be able to stop. And I don't really want to talk about him, you know?'"

Someone she may gush to about Cooper? His mom Gloria! A source revealed that they hang out when Bradley is busy. Waterhouse wants his mom to know she's in the relationship for the right reasons.

After American Sniper, Cooper will be seen next in three movies this 2015. First off is Aloha, where he will be paired with Emma Stone and directed by Cameron Crowe. Next is an Untitled John Wells project, where he plays as a chef. Finally is a reunion for the fourth time around with Jennifer Lawrence in the movie Joy.
