'Ready To Pop': Maci Bookout Shares Almost-Full-Term Baby Bump Photo

The 'Teen Mom OG' cast member will welcome her third child this month

Maci Bookout's due date for kiddo number three is just around the corner (May 30, to be exact), and the Teen Mom OG cast member is sharing a glimpse of her nearly full-term belly.

"This momma is ready to pop. #happymothersday," the Tennessean captioned the snapshot above, which finds her burgeoning bump front and center as she celebrates the holiday. Looks like little Maverick Reed is almost ready to make his highly anticipated debut -- and meet his mama, dad Taylor and siblings Bentley and Jayde. Won't be long!

Be sure to offer your well wishes to Maci in her final stretch before welcoming her son -- and to hear more about from Maci and Taylor about this pregnancy, watch the clip below!
