Looks like Teen Mom's Leah Shirley is about to get a visit from the Tooth Fairy! And when we say "The Tooth Fairy," we most definitely mean her dad, Gary Shirley. This lovable watermelon farmer better slip into a tutu and grab a magic wand, because his darling daughter lost her very first tooth and the time has come to put it under her pillow in exchange for some dough.

"Leah lost her first tooth today!" Gary tweeted on October 29. "Yay for @leah_leann."

Tear! Can you believe Leah is old enough to be losing her teeth? It seems like just yesterday that this gal was making her grand debut from Amber Portwood's lady parts on MTV's 16 and Pregnant! Leah's growing up so fast, and sadly Amber has missed out on some of her little lady's most important milestones.

Not only did Amber miss Leah's first loose tooth, she's missed holidays, birthdays, and other big events in her life. The good news? Amber is being released from jail on November 6, which means she'll be reuniting with Leah just in time for Thanksgiving!

By the way, does anyone else think Amber should tattoo another full-sized portrait of Leah's face on her body — this time with a gap-toothed smile?
