Chace Crawford, Penn Badgley and Shawn Pyfrom celebrate Penn’s 21st birthday at TAO in Las Vegas.

He’s only 21????

I am so old.

Also, everyone in this picture is really sober.

The glazed look in their eyes?

Food coma.

JC Chasez was there, too, but I can’t even really handle the weirdness of that fact to elaborate much on it. I guess he just likes younger men. You think he’s with Shawn these days? I think so.

HAPPY 21st BIRTHDAY, PENN!
