Not every start or hearthrob from the turn of the century remains a star or gets their happily ever after. For proof, look no further than Aaron Carter’s many, many problems.

But, as so many of us hoped back in the late ’90s, both Britney Spears and Justin Timberlake are now living their best lives. Just … not with each other. And that’s okay.

In fact, Justin Timberlake and Jessica Biel are immensely precious and adorable together. Look at what they each wrote for their 5-year anniversary!

It’s weird, thinking back on it.

Some celebrity couples, like Ashton Kutcher and Mila Kunis, seem almost preordained.

(One could argue that the writers from That ’70s Show set the couple up)

Selena Gomez and Justin Bieber, who are thankfully no longer together (although they’re talking again), both rose to fame around the same time. It was sort of a natural fit.

Other couples aren’t quite what you would have expected, back when they first became famous.

Justin Timberlake was on The All-New Micky Mouse Club and then skyrocked the fame as the most thirsted after member of NSYNC when they launched in the ’90s.

He’s been an enduring sex symbol ever since, though he’s definitely more in the “DILF” category now. That’s how time works, but it’s been kinder to him than to many of his former bandmates.

And then there’s Jessica Biel, who might still be best known for her role on that old Christian family drama, Seventh Heaven.

But in 2007, they met at the Golden Globe Awards. That, according to witnesses, is when “sparks flew.”

We don’t believe in love at first sight, exactly, but overpowering thirst at first sight can absolutely blossom into genuine love.

Because just look at them now.

On October 19th, 2012, Justin Timberlake and Jessica Biel got married.

And that means that, yes, yesterday was the beautiful couple’s 5 year wedding anniversary.

Justin Timberlake left 

“#TBT to a late night freestyle session on a break in the studio — YES I’ve been back in the studio cooking!”

So he’s back in the studio for real, but he shared some black-and-white throwbacks of himself in the studio.

“But, today is even more special for me because five years ago, on this day, I became the luckiest man in the world when I exchanged vows with my best friend. This song was our first dance.”

Awwww! That is so cute, you guys!

“To my beautiful @jessicabiel : You have taught me so much about what a true love means.”

Some things you have to do in order to properly understand them. Like computer programming. Or true love. Or surgery.

“I can’t put into words what these last five years have meant to me, so… ‘Listen to the melody ‘cause my love is in there hiding…'”

Hey, artistic expression is sometimes the best kind of expression.

He finished with the tags:

“#Happy5thAnniversaryWifey #ASongForYou”

That’s so sweet! Corny, but sweet.

It has to be surreal to be married to a sex symbol, even if you yourself are also a big-name actress and major Hollywood hottie.

Their son, Silas Randall Timberlake, is only two years old.

One day, he’s going to watch the Shrek movies — all 9,000 of them, by that point. Before he gets to the one where his father provides a guest voice, he’ll see Princess Fiona sleep in her childhood bedroom where a poster reads “Sir Justin.”

Like … that level of cultural impact that Justin Timberlake has had … it just has to be a little weird for the people who know him best.

Cool, but weird.

Jessica Biel, however, just counts herself lucky.

Her message of love and adoration for Justin was much more succinct.

“How lucky am I? Even if he’s initially skeptical, he always gets extra for me. #5”

She’s talking about him dancing goofily along to music with her, but it sounds like he’s like that all of the time.

And that’s so good to hear.

It sounds like Justin Timberlake might be playing the Superbowl Halftime Show this year.

You know, the musical performance that happens to have some sort of sporting event before and after it. The Halftime show is where the action is. And it’s where stars are born — remember Left Shark?

Well, Justin Timberlake has already been part of a similarly memorable Halftime Show … when he and Janet Jackson and an alleged ‘wardrobe malfunction” shocked audiences with Janet’s bare breast.

That was back in 2004. And we’re pretty sure that it was the origin of the term “wardrobe malfunction.”

Many people feel that, because Janet was blacklisted from so many networks in retaliation, Justin shouldn’t get to come back unless she can.

While that sounds fair to Janet, it sounds unfair to JT, you know?

We don’t know whether Justin should play the Halftime Show, but we think that Jessica Biel would be all for it.
