Hollywood marriages aren’t always built to last.

For a whole host of reasons, from busy schedules to way too many resources to certain temperaments to looks and wealth and rumors … celebrity relationships tend to crumble before our eyes.

So it makes sense that when you last a long time, you want to show it off. Nicole Kidman and Keith Urban are doing just that with a series of adorable selfies — because they’re celebrating their 11th anniversary.

Keith Urban and Nicole Kidman, Cheek to Cheek

To be clear, 11 years is a long time to stay together for a regular, run-of-the-mill, non-celebrity married couple.

In Hollywood years, it’s like these two have been married for the better part of a century.

But somehow Nicole Kidman and Keith Urban (the one who isn’t Nicole Kidman) have managed it.

And they’ve done so despite major disagreements about where to live. That takes work.

Then there’s the baggage that they have.

We don’t just mean regular relationship baggage or fame baggage.

We don’t even mean the fact that the Oscar-winning actress and the Crunchy … sorry, Country music singer come from different worlds.

(Like, Blake Shelton and Gwen Stefani are closer than ever and they also come from different worlds)

Nicole Kidman also had a famous relationship with Tom Cruise.

The rest of her life is haunted by the specter of Scientology.

She doesn’t speak about the Church, but we all know how this works.

The kids that she and Tom adopted together are still Scientologists.

They’re adults, but were Nicole to ever speak ill of the Church or very likely of Tom, she’d be declared a Suppressive Person, and she’d never get to see them.

It can be a strain to be interviewed constantly and have to give a tight-lipped smile when people ask about a subject that makes you want to scream.

And that tension from walking a verbal tightrope can impact both members of a couple.

But it looks like they’re not letting it touch them.

Also, though they’re both celebrities, there’s something of a fame disparity between the two.

Because Nicole Kidman isn’t a niche celebrity. She’s, you know, world-famous as an actress.

Toby Keith sometimes gets confused with another Country singer by people who aren’t in that particular music fandom.

Remember, Keith Urban is the one married to Nicole Kidman.

Toby Keith is the one who played for an all-male audience in Saudi Arabia.

But Keith and Nicole look happy and also way younger than they actually are.

Because Nicole is 50 and Keith is 49.

Does time mean nothing to these two?

Yeah, these two are really adorable.

Some other couples have lasted for a really long time, but in a world where Brangelina is divorcing, staying married means really beating the odds.

(Though rumor has it that Brad Pitt is hoping to win back Angelina Jolie, so … we’ll see how that goes)

Yeah, these are really adorable.

Also, who says that old people can’t be cute, you know?

And, not for nothing, but this is such a level-headed, grounded way of celebrating an anniversary.

As far as we know, they didn’t swim around in a champagne pool or do any other ridiculous rich people stuff.

When you’re together for over a decade, sometimes happiness with your partnership is just enough, you know?

You don’t need all of the rest.
