Maci Bookout and Taylor McKinney are getting married on tonight's new episode of "Teen Mom OG." During the show's season six finale, the longtime couple will be seen tying the knot in front of several members of their family and friends.

In a sneak peek of their big day shared by Us Weekly on November 28, Bookout and McKinney are seen preparing for their wedding as their family, friends and co-stars, including Catelynn Lowell and Tyler Baltierra, arrive to their venue in Tallahassee, Florida. As McKinney and his groomsmen, including Bookout's oldest child, son Bentley Edwards, 7, arrive at the church on a red golf cart, Bentley's dad, Ryan Edwards, and his paternal grandparents, Larry and Jen Edwards, are also seen walking into the church.

Once the men are inside, Maci Bookout is seen arriving on her own red golf cart with a male driver and female friend. Following behind her are her bridesmaids and her daughter, Jayde Carter McKinney, 1.

Maci Bookout met her husband Taylor McKinney in 2012

After "Teen Mom" came to a temporary end, Bookout met McKinney through friends and they quickly began dating. Then, in May 2015, their first child, daughter Jayde, arrived. Although no one expected Bookout to get pregnant for a third time so soon after Jayde's birth, she confirmed she was expecting earlier this year and in June, her third child, son Maverick Reed McKinney, was born -- just one day after Jayde turned 1-year-old.

Maci Bookout made nice with Ryan Edwards before her big day

Maci Bookout and Ryan Edwards have been known to feud from time to time but during last week's show, Bookout and McKinney sat down with Edwards and his new girlfriend, Mackenzie Standifer, for a meal. As expected, Bookout was hoping to get to know Standifer better before the woman attended her and McKinney's big day.

For more of Maci Bookout and her now-husband Taylor McKinney, as well as the rest of their co-stars, including Ryan Edwards, don't miss tonight's "Teen Mom OG" season six finale at 9 p.m. on MTV.
