9 Incredible Celebrity Couples You Never Knew Dated

Lena Dunham is clearly a girl after our own heart. While enjoying a weekly peruse of a blog dedicated to former Hollywood couples, she spotted a picture of current musician boyfriend Jack and Scarlett Johansson. "I was like, 'My mind is going to explode', I really did think I was hallucinating," the actress and Girls creator said of her unexpected discovery to Grantland Channel. And thank you Lena, for blowing our minds too.

We thought we were hallucinating when we found out Ashton Kutcher and Mad Men's January Jones were once an item. The former couple don't seem to have aged a day since either..

We didn't even know these Hollywood stars were a couple, and yet we're already wishing they were still together. And they could have saved a fortune on clothes.

Judging by the ensembles on these two, anything was possible in the early '90s....

Celebrity circles sure seem incestuous... Remember when Kim K and Mariah Carey's now-ex-husband hooked up? Neither did we.

Their children would have had incredible hair.

This couple certainly made a cute one. And it sadly completely passed us by.

They practically had matching mullets...

Ok, we remember these two dating like it was yesterday, we just wanted bask once more in their adorableness.
