The New Year's celebrations continued for Catelynn and Tyler Baltierra well after the clock struck midnight: The "Teen Mom OG" couple feted their darling daughter Novalee with a memorable birthday bash during the past weekend.

The MTV munchkin -- who turned the big 0-1 on January 1 -- was the lady of the day at a pink-filled party with all of her loved ones. And judging by the visuals from the event, the tiny tot -- clad in a T-shirt showcasing her age, a purple flower pin and a precious matching lavender tutu -- really enjoyed her special afternoon.

"Happy first birthday tootie!!" the proud mama captioned the video above, featuring sweet Nova being serenaded and presented with her very own frosted dessert. Ahh, nothing quite like having that first bite of cake when you're the guest of honor.

Cate also couldn't help but reflect on the milestone occasion and gushed to her petite gal that "your daddy and I love you beyond belief! You made this year even better! Happy birthday!" My, how time flies...

Check out more special snapshots from the bash below, and be sure to catch Novalee -- as well as her parents! -- on the two-hour premiere of "Teen Mom OG" tonight at 10/9c!
