Our favorite Teen Mom baby daddy, Tyler Baltierra, just celebrated his 21st birthday! As you might expect, this lovable studmuffin spend the evening partying up a storm with his fiance Catelynn Lowell, and yes — he boozed it up like there's no tomorrow.

Not only did Tyler chug down a few brewskis, he imbibed in all kinds of hard alcohol! Sigh, this is like Lindsay Lohan (circa right now) all over again. "Dude I feel like death!" Tyler tweeted on January 13. "Whiskey, tequila, vodka & beer don't mix too well. Thank god i have @CatelynnLowell to take care of me heart her #21."

Luckily, Catelynn was up for the task! "yea hunnie you deff needed some care this morning!" she tweeted to her man. "Love you baby!!! #alwayshere."

Sob, these two are adorable even when they're hungover. And by the way — can you believe Tyler is already 21? Seems like just yesterday that he was growing out his experimental chintee … sigh.
