This country gal-turned-reality TV starlet has accomplished a lot in her 18 years. Not only is she a great mom to baby Gannon (born Sept. 12, 2011), but she's also a skilled cheerleader, equestrian, and hair stylist. Mackenzie says that enrolling in cosmo school was the "best decision [she's] ever made."
Mackenzie's not married yet, but she and baby daddy Josh McKee definitely plan to tie the knot when they're a little bit older. She is so mature for her age!
