If youve ever seen Derek Hough dance, you know hes got some serious skills. But apparently, he has some smooth moves in the love department, too. The World of Dance judge has been posting (ridiculously cute) Instagrams of his girlfriend Hayley Erbert a lot lately, so peopleincluding his fellow judgesare dying to know more BTS info about their relationship.

The best place to start? Derek's Instagramit's full of cute pics of him and Hayley. Case in point: He posted this simple, yet meaningful post on Valentine's Day.

Clearly, his and Hayley's romance is serious (on top of being seriously adorable). But before you start wondering about any wedding bells, you're probably wondering who is this Hayleyand how did she dance her way into Derek's heart?

Heres everything you need to know about Derek Hough's girlfriend:

They met on Dancing With The Stars.

ICYMI, Derek was a dancer on DWTS for years before joining the WoD fam. That's where he met Hayley, a troupe dancer with the show. The two even danced to Ed Sheerans "Thinking Out Loud" on DWTS Live in 2015.

Hayley also shared a #tbt Instagram post in May 2017 that showed her and Derek onstage, looking all steamy together. "Cant believe this was 3 years ago," she wrote. So clearly, theyve had chemistry for eons.

Its hard to say exactly when they started dating.

Despite all those fireworks, the two didnt actually start dating until 2016, according to Closer Weekly . But others say they started dating as early as 2015 (which, tbh, does make sense with Hayley's Insta).

But now, they can't get enough of each otherliterally.

The couple is quarantined together in Los Angeles, where they've been making allllll the TikTok videos to keep themselves busy (see: Derek's acoustic piano performances ). They even made lovey-dovey ~content~ during an afternoon in the pool.

Back in March 2020, they went all out and made a "Flip the Switch" video, and even released a behind-the-scenes look at Derek's first experience with lipstick.

Still, since they can't perform beyond at-home performances (like the Disney Sing-Along, wink wink), they found themselves doing the Chubby Bunny marshmallow challenge "out of pure boredom."

They recently did not one, but two Disney singalongs.

The couple played Belle and Lumiere and sang "Be Our Guest" during the first Disney Family Singalong, the COVID-19 special produced by ABC and hosted by Ryan Seacrest in April. For the second special, they sangand choreographed an intense dance routineto "Step in Time" and "Supercalifragilisticexpialidocious" from Mary Poppins.

Haley's in touch with her mystical side.

During quarantine, she's been pulling out her tarot cards and journaling almost every night. She even explained on IG that one of her favorite things about staying home has been her almost nightly "moon deck ritual."

Derek and his sister Julianne helped launch Hayleys career.

Hayley was hired to go on a Move Live tour with Derek and Julianne Hough in 2014. And while she was performing, she caught the eye of a producer for DWTS who recruited her for the reality competition show, Heavy reports.

They love spending the holidays together.

Hayley shared an Instagram of herself and Derekin matching PJs, no lesscelebrating Christmas together in 2018. (Derek's WoD costar J.Lo and boyfriend A-Rod posted a similar holiday pic, too). In the pic, the two jokingly pose with a cat in front of a fire, and its all kinds of adorable.

Hayley is a huge fan of a certain Canadian singer.

Sorry, Beliebers, but it's not Justin. Last year, Hayley admitted on Instagram that shes obsessed with Celine Dion, sharing this hilarious video of herself and Derek rocking out to "Its All Coming Back to Me." If that isnt love

They support each other's work.

While Derek left DWTS a few years ago, he's "still paying close attention" to the show to support Hayley, and Hayley's also attended some World of Dance tapings to support him, according to ET .

And then Derek recently shared this

Nuff said, right?

Hayley takes the lead in the kitchen.

Derek's Instagram is filled with videos of Hayley cooking (most likely ridiculously nutritious meals to fuel all that dancing). In one particularly sweet vid, he serenaded Hayley with "Shallow" from A Star Is Born while she was busy in the kitchen:

And then there's this:

Theyre so in love its ridiculous.

Derek has repeatedly said on Instagram how much he loves his gf. And when she was in a bus crash on DWTS Live, he Instagrammed a photo of the two of them from his sisters wedding and wrote, "Im so thankful my love is safe."

Hayley's a Libra.

Born on October 11, Hayley's a total Libra. And since Derek's birthday is May 17, that makes him a Taurus. While their zodiac signs aren't perfectly compatible , Libras and Tauruses are the best match in the bedroom.

Not that it really mattersDerek loves Hayley no matter what. In a sweet birthday Insta, he wrote, "Happy birthday to my love. You fill my heart with so much joy. I love our crazy adventures together or just sitting on the couch with our bodies entangled watching a movie." Awwww.

People really, really want them to get engaged.

Like, a lot. After Julianne got married, E! asked Derek if he might be next. "It's not something we really talk about so much right now," he said. "It was a wonderful week to be with [Hayley] and experience love." Still, he added, "I don't want to be an old grandpa when I start having kids... After that wedding, I'm like, Who knows?' You feel the love."

Ryan Seacrest also straight-up asked Derek in July 2018 if he thinks about getting engaged, and Derek had this to say: "Yeah, sometimes. Sometimes. But you know whats funny? Theres so many people getting engaged and married in my circle [right now], and Im just letting them enjoy that, so my time will come. Well see when it happens."

Oh, and J.Lo's apparently been wondering when he's gonna pop the question, too.

On the set of World of Dance, Derek made a "dad joke," and J.Lo told him shed thought hed be a good dad someday. "And then she said, 'So, why arent you [a dad]? And why arent you married?' Im like, 'Oh god!'" he recalled in the above video.

Then, she apparently asked Derek, "Well, do you want to get married?" And he said, "Well, yeah, I think I do." To which she responded (in classic J.Lo no BS fashion), "Oh, you think you do? Youre one of those?" Derek explained, "I was like, 'Well, hold on! Let me finish'

Okay, Derek, imma let you finish, but only if you keep posting more adorable Instagrams of Hayley in the meantime.
