Model-actress Suki Waterhouse really wants to be Mrs. Bradley Cooper.

A source told Us Weekly that the 23-year-old, who started dating Cooper in March 2013, wants her beau to propose to her soon and has been talking to him about the idea of marriage. 

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

Waterhouse has already formed a close relationship with Cooper's mother Gloria.

"They hang out when Bradley is busy. She wants Gloria to know she's in the relationship for the right reasons," the source added.

Cooper and Waterhouse first stepped out as a couple in December 2013 at the New York City premiere of "American Hustle."

But a ring isn't the only thing that Waterhouse is craving - the actress is also thinking about babies. 

"I really like the idea of having kids in not too long. Not, like, now. And not next year. But in not too long," Waterhouse told Elle U.K. in January 2013. "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?'"

The news comes after OK! Magazine published a story last week, claiming that Waterhouse wanted to confront Cooper's "American Sniper" co-star Sienna Miller about her relationship with her boyfriend. 

"Suki is so fed up with Bradley's relentless gushing about Sienna's talent, it has caused some huge fights," a source told OK! Magazine (via The Mirror). "Suki told him that if she walks by Sienna at the Oscars, she is going to tell her to stay away from her man."

The insider continued, "Sienna wants to stay as far away from Suki as possible, the last thing she wants is some trashy drama and to be called a home wrecker by a twenty something year old girl at such a classy event."

Cooper is currently filming the biopic "Joy" and Netflix's satirical comedy series "Wet Hot American Summer: First Day of Camp," while Waterhouse is working on the horror-comedy-romance film "Pride and Prejudice and Zombies."
