The key difference between your twenties and your thirties, anyone who’s celebrated the big 3-0 will concur, is stamina when it comes to staying out late.

Take Jessica Biel. On Wednesday night the 36-year-old actress was out celebrating husband Justin Timberlake’s 38thbirthday in New York City. As JT revealed via an Instagram video, Biel stole a nap at one point during the night.

Timberlake whispers “Happy birthday to me” before panning the camera to his wife, who is leaning her head on the window with her eyes closed.

“I’m just preparing for our big night out. Just preparing,” she replies when she realises she’s been caught.

A little bit of digging revealed the couple went to see To Kill A Mockingbird on Broadway that night. It’s not clear if they went for dinner or drinks afterwards, but judging from this video, we wouldn’t be surprised if they just called it a night.

Party while you’re young, kids.
