Just last week, Justin Bieber dropped his highly anticipated single "What Do You Mean." He performed the already popular song for the first night at last night's VMAs and then debuted the sexy music video shortly after. In the video, Bieber strips down to his jeans and Calvin Kleins as things between him and model Xenia Deli, who stuns in revealing red lace lingerie, get pretty steamy.

While a shirtless Bieber has girls everywhere going crazy, people can't help but wonder who the lucky lady is. While the two have been rumored to be dating in the past and she's done some pretty high-profile modeling gigs, there's still a lot we don't know about the 25-year-old beauty, besides the fact that her body was pretty much made to rock lingerie. Here are five things you need to know about last weekend's most talked about model.

1. She's modeled for Playboy and Victoria's Secret

This isn't the Moldavian model's first big break. Back in 2012, she posed in a clothed photoshoot alongside Bruno Mars for Playboy, according to Daily Mail. She is signed with Elite Model Management and has also has appeared on the cover of magazines like Sports Illustrated, Elle Romani and loveFDM. She's even the former face of Victoria's Secret's Pink collection.

2. She's been in music videos before

She has been featured in a few international artists' music videos in the past, including Ionel Istrati's "Wake Me Up" and Calvin Harris' "Thinking About You," according to Hollywood Life. She also briefly appeared on Mindy Kaling's "The Mindy Project" in the episode "You've Got Sext."

3. She's extremely comfortable showing off some skin

As if modeling for Playboy and Victoria's Secret wasn't enough proof of this, her Instagram page sure is. She posts tons of photos of herself to her 155k followers in lingerie, bikinis, and even a few nude and topless shots.

4. She stays in great shape

Her body is a clear giveaway of this, but she loves to work out. Her Instagram has quite a few impressive videos and photos of her working out at the gym and doing yoga.

5. Bieber thinks really highly of her

They also may be dating as they've been spotted getting cozy while out together, but they haven't confirmed anything. Just last week, Bieber was on "On Air With Ryan Seacrest" when he told the host, "She is so beautiful, but she's also such a sweetheart. Like she's easy to be around and stuff. Do you see how I can't put this [photo of her] down right now? This is inspiration right here.
