"Happy birthday to my number 1 gal @leah_leann love you so much! My little blessing. See you after school for special dinner and party tomr," Leah's father Gary Shirley tweeted on November 12. He also tweeted that he brought pizza and cookies to her class at school. Cute!
This has been an extra special year for the little one as her mom was released from prison just days before her birthday last year. The proud mama has taken to Twitter to share some pics of the fun adventures they've had since they were reunited.
Amber also shared this photo on her Facebook page with the caption "officially 6 years old" along with two heart emojis.
Based on what we've seen on Twitter, it looks like they're in the middle of filming for the upcoming season of Teen Mom right now, so hopefully we'll get to see some of Leah's birthday festivities on the show when it returns in 2015.
It's going to be so fun to see Leah and Maci Bookout's son Bentley on the upcoming season and we're also super excited to meet Catelynn Lowell and Tyler Baltierra's daughter!
