Paulina Gretzky recently posted one of the most amazing post-baby body photos we've ever seen. In the photo, the new mom was lounging by the pool rocking a skimpy black bikini, showing off her teeny tiny waist.

As someone who gave birth to her son Tatum just five months ago, the 26-year-old has the whole world talking about how incredible she looks.

So who exactly is Paulina Gretzky? And how does she stay in such great shape at all times?

Here's five things you need to know about this bathing beauty.

1. She's married to pro golfer Dustin Johnson

The two began dating in January 2013 and got engaged shortly after in August. They first met at a dinner hosted by her parent's and were "friends for a long time before they started dating," according to E! News. At the time of the engagement, Johnson posted a photo of the gorgeous, and enormous engagement right to his Twitter with the caption "She said yes!!!" Johnson currently plays on the PGA tour and is one of the longest drivers on the tour.

2. Her Dad is hockey legend Wayne Gretzky

Ever heard of him? Wayne is known as "The Great One," and may very easily be one of the greatest hockey players ever. He played for twenty seasons in the NHL for four different teams. He holds the record for most goals in regular season games, as well as plenty of others. Not only is her father well known, but so is her mother! Gretzky is the daughter of actress Janet Jones

3. She's a singer

In 2004, she sang the Canadian National Anthem during the 2004 World Cup of Hockey. She later told Complex in 2012 that, "People might think this has been easy for me, but I've been working hard at singing since I was 16. I went to Interlochen. I studied opera. I've paid my dues." Her most popular song was "Collecting Dust" which appeared on MTV's "Laguna Beach: The Real Orange County." It has also been released on iTunes.

4. She's a model

She skipped college in order to pursue her singing and modeling career. She made her modeling debut on the cover of Flare magazine, and has appeared on a few other covers, including Golf Digest, since. She has also posed for Maxim, according to ABC news.

5. She's consistent about working out

Though she admits she is naturally thin, she does not restrict herself when it comes to indulging. She adores eating pizza and cheeseburgers, according to her interview with Golf Digest, but she makes sure to not eat them too often. In the issue, she talks about six self-improving exercises that are meant for golfers that she does regularly. She hits the gym five to six days a week and makes sure she always stretches before and after her workout. She also loves to do squats and lunges to keep her backside and legs toned. She used to do more cardio, like running, dancing and kickboxing, until she hurt her knees. Now, she tries to do workouts that aren't so harsh on her joints, like yoga. She's a firm believer in 70 percent of your health being dieting, and the remaining 30 percent being exercising.
