Jessica Biel proves that motherhood is not always sunshine and rainbows and unloaded her thoughts on those 'terrible twos' kids go through on The Late Show with Stephen Colbert.

And it's kind of hilarious.

The worst of all? When Silas wakes up in the middle of the night.

 "You know, if you wake my kid up in the middle of the night by accident, you're dead to me."

Jessica then assured Stephen it was never her friends waking the kids up in the middle of the night but rather Justin's friends.

"My friends are quiet, demure, modest. He's a wild musician."

OMG! So good. That's totally going to be me talking about Michael's friends some day.
