Who Is Bradley Cooper’s New 20-Year-Old Fling?

Sorry, ladies, Bradley Cooper may be (temporarily) off the market.

On Monday, the former Sexiest Man Alive was spotted in Boston with rumored girlfriend, model Suki Waterhouse, and the duo seemed to be flirting as they strolled around the Common.

Cooper, 38, and Waterhouse, 20, were first photographed together on Feb. 12 as they were leaving the Elle Style Awards in London.

"Yeah, they are seeing each other," a source close to the "Silver Linings Playbook" actor confirms to omg!. "They have been talking since they met."

"Bradley is really busy with work, and [Suki] is very up and coming in the fashion world, so they are just seeing where it goes," adds the source. "They are having fun."

What about the 18-year age difference between the two?

Back in January, Cooper denied he was dating Jennifer Lawrence, saying he was old enough to "be her father."(FYI, the age gap between Cooper and Lawrence is only 16 years.)

So who is Suki Waterhouse? Here are five things to know about the lucky girl on Cooper's arm.

She's a British model: Waterhouse -- who goes by Suki Alice http://www.sukialice.com in the fashion world -- dropped out of school at age 16 to start her modeling career. She has walked in shows at London Fashion Week and has appeared in British Vogue. "I love modeling, but I have to do other things too," she told Love magazine. "It's important not to take it too seriously."

She's a quadruple threat: Aside from modeling, Waterhouse is an actress, a photographer, and musician. "I'm not looking to be a pop star or anything, but it's nice to be creative," she said to Love. "I feel like I have to do that, otherwise I'd go a bit nuts."

Ex factors: Apparently, the gorgeous blonde usually goes for musicians! Waterhouse dated Luke Pritchard, the frontman of the band the Kooks, but they split in 2011 after a year together. She then dated Miles Kane, lead singer of the Last Shadow Puppets. Some outlets reported that she and Kane were dating when she was photographed with Cooper after the Elle Style Awards, but the Daily Mail claimed that they had split a few weeks prior.

Family scalpels: She is the daughter of Norman Waterhouse, philanthropist and plastic surgeon to the stars.

Notable quotables: Waterhouse has two quotes on her Facebook page: "I respect anyone who can wear anything well, it doesn’t matter what they’re wearing, they just wear clothes with attitude" and "You accept the bit that heals the wound."

Cooper is currently in Boston filming the Untitled David O. Russell/Abscam Project, which will reunite him with Lawrence; it also stars Christian Bale, Amy Adams, and Jeremy Renner.

A rep for Cooper is not commenting on the latest romance rumors.

The Oscar nominee previously dated "Star Trek Into Darkness" star Zoe Saldana, but the two amicably split late last year. Cooper has since been linked to actress Alice Eve and falsely to Jennifer Lawrence and Taylor Swift.
