If you can believe it— and honestly we can't, considering all the crazy shit she gets into— Lindsay Lohan is only 26-years-old. She celebrates her birthday today, but had a little born day soiree last night at Bootsy Bellows in West Hollywood.

But get this, she stayed sober for the whole thing! Imagine that.

"She sat at her table close to the DJ," a source told Us Weekly. "There was a ton of alcohol at Lindsay's table, however she didn't appear to be drinking... she danced all around with her friends."

There were even cupcakes and a point during the shindig where they sang Lindsay "Happy Birthday."

It all sounds so... normal. Seriously, WTF?
