Their romance may be new, but Joe Jonas and Gigi Hadid have already stolen our hearts along with each other's. The cute couple, who've been dating since about May, not only have model good looks (seeing as Gigi is one, naturally), they always seem super comfortable together and have wicked senses of humor.

These two make for one smokin' hot duo, but we love them for way more than that. Here are six reasons why we think Joe and Gigi make the perfect pair:

1. They're proud of their relationship.

Joe and Gigi aren't hiding the fact that they're coupled up. Though they do so selectively, both share photos of each other on Instagram -- some of which are a little TMI, but what can you do.

They've also attended major events together, like the U.S. Open, and haven't been shy about PDA.

Would you be coy about smooching/hand-holding/using suggestive captions in your Instagram photos if you looked like these two? That's what we thought.

2. They support each other.

They're clearly both very proud of the other's work. Joe was spotted all around Manhattan supporting his 20-year-old girlfriend as she walked on multiple runways at New York Fashion Week, including Anna Sui, Jeremy Scott and Tommy Hilfiger.

Despite being busy with her impressive modeling career, Gigi still took time out to support Joe's endeavors. He posted a video on Tuesday of his lovely lady (and Ciara!) lip synching to "Cake By The Ocean," the first single from his new band, DNCE.

3. They're family-focused.

Both have siblings in the same industries. Joe was in the band, the Jonas Brothers, for years with his two brothers, Kevin and Nick. Though Kevin has removed himself from the spotlight, Nick has had an extremely successful solo career that Joe frequently lauds. As for Gigi, she's an awesome big sister to Bella Hadid. Both often walk in the same shows and are part of Taylor Swift's girl squad -- even more impressive since the "Bad Blood" singer is Joe's ex-girlfriend.

They also support each other's families and band together for big events. Even though they had only been going out for a couple of months at the time, Gigi schemed with Nick to throw Joe an awesome surprise party for his 26th birthday in September -- an epic match between their buddies and the Los Angeles Galaxy soccer team!

Happily, Nick digs his brother's new relationship. "I'm happy to see my brother happy," he tells ET. "It's a great thing. You love seeing your family happy. She's a great girl." And Bella is pretty fond of Joe. "I love him to death," she says. "He's amazing!"

4. They hang with each other's friends.

"I think they're a great couple," Hailey tells ET. "He's really sweet, and she's really sweet. I think they're good for each other."

Plus, Cara even gave the duo an It Couple nickname -- G.I. Joe! How freakin' cute is that?

5. They're mature.

If there's any jealousy here, the couple hides it very, very well. The two hung out with Joe's ex, Taylor, (see No. 3, above) and the singer's new boyfriend, Calvin Harris, in July. Most people don't double date with their former lovers, but hey, Young Hollywood is not comprised of most people.

6. They're simply adorable.

There's plenty of evidence of this, ranging from goofy:

To touching (both literally and figuratively):
