In the wild world of Hollywoodland, celebs get together and break up almost as often as they change their underwear — so when a young couple actually sticks it out for more than a couple of years, we take notice. Such is the case of Gigi Hadid and Zayn Malik, who have been a thing since 2015. At this point, these two are obviously more than just a fling, and we are so here for it.

They're gorgeous, in their 20s, talented and filthy rich, all of which is a recipe for a short, intense affair that ends in a nasty (and very public) breakup, but Hadid and Malik seem to be in it for the long haul. But why? It could be the fact that they are completely compatible and have a lot in common.

Here's why we're pretty much convinced Hadid and Malik were made for each other.

1. They're both loyal

Even after Hadid got raked over the coals for a totally distasteful post on Snapchat, Malik was there to back her up — causing him to get backlash for it himself.

And when Malik had to cancel money-making appearances and performances due to crushing anxiety? Hadid was there for him too.

"Z — I've seen the battle you go through and the way you fight to get to a place that allows you to get up there for your fans," Hadid wrote on Twitter. "Your bravery in those times makes me proud, but your honesty last night proved what you're all about, being real. Human recognizes human... Your talent and good heart will never lead you wrong. Love you and so proud of you always."

2. Those aren't their real names

It's not as though this is exactly a surprise. Many celebrities go by stage names — Demi Moore (Demetria Guynes), Ben Kingsley (Krishna Pandit Bhanji), Portia de Rossi (Amanda Lee Rogers), Michael Caine (Maurice Micklewhite), Whoopi Goldberg (Caryn Johnson), etc. Hadid and Malik join this ever-growing group of Hollywood name-changers, born Jelena Noura Hadid and Zain Javadd Malik, respectively.

3. They seriously get into the Halloween spirit

For Halloween in 2015, Hadid slayed as the bad-girl version of Sandy from Grease.

The year before, Malik and his then-fiancée Perrie Edwards went all out as Edward Scissorhands and Cleopatra.

4. They are both earth signs

There are three earth signs in the zodiac: Capricorn, Taurus and Virgo. Malik, who was born on Jan. 12, is a Capricorn. Hadid, who was born on April 23, is a Taurus. According to Astrology.com, earth signs are "earthy," sensual and often laid-back. They can also be stubborn. The fact that they are both earth signs could bode well for these two, given that they are considered a power duo.

5. They have blended heritage

Born to Mohamed Hadid and Yolanda Foster (née Van den Herik), Hadid is of Palestinian and Dutch ancestry. Malik's father, Yaser Malik, is British-Pakistani and his mother, Tricia (née Brannan) Malik, is English. Malik has said he had trouble fitting in at his first two schools due to his mixed heritage.

6. They're close to their big families

Hadid and Malik both have large families. Hadid has two younger siblings: sister Bella and brother Anwar. She also has two older half-sisters, Marielle and Alana, on her father's side and five stepsisters from her stepfather. Her social media pics often include her family, like this pic of her dad.

Malik has three siblings: one older sister, Doniya, and two younger sisters, Waliyha and Safaa. And Malik's childhood photo and new album cover is too adorable for words.

7. They have "a type"

Hadid clearly harbors a fondness for hot up-and-coming musicians. Her first serious public relationship was with Australian singer/songwriter/entertainer Cody Simpson, which ended in May 2015. She then began dating Joe Jonas, who she broke up with in November.

Before Hadid, Malik also fancied musicians. He dated fellow X Factor contestant Rebecca Ferguson for several months, after which he began dating Perrie Edwards of Little Mix in early 2012. In that respect, Malik is kind of breaking with his usual type with Hadid (but not really if you read No. 9 below).

8. They have both been the subject of controversy

As crazy as it seems, Hadid has sparked criticism for being too large for the runway. Yes, you read that right. It's ridiculous, we know. This reached fever pitch following Milan Fashion Week when Hadid walked in the Versace SS16 show, and critics claimed that — at size 4 and "curvy" — she isn't fit enough to strut in a high-fashion show. These detractors claim she should stick to Sports Illustrated and Victoria's Secret shows. To her credit, Hadid responded with total class in an open letter on IG.

Malik is no stranger to criticism, either. He was dubbed the bad boy of One Direction before he left (which was a controversy in and of itself) and on more than one occasion was caught with, erm, recreational substances. He is also a Muslim who is routinely derided by conservative Muslims who feel there are contradictions between the doctrine and his lifestyle.

9. Oh yeah, & they can both sing

This is the real ace up the sleeve when it comes to being a celebrity power couple — Hadid and Malik share many talents, one of which might be singing. Hadid reportedly tried to make it in music before heading to the runway (singing backup for Josh Groban almost 10 years ago), and well, we already know that Malik's musical talents are kind of a big deal. If the beautiful couple ever decides to release a duet, you heard it here first.
