Maci Bookout Teen Mom OG
Maci Bookout starts wedding planning in episode 4 of “Teen Mom OG.” MTV

Maci Bookout had a lot on her plate the last time “Teen Mom OG” viewers saw her but that won’t stop her from beginning to plan her wedding to Taylor McKinney in next week’s Season 6 installment. One of MTV’s sneak peeks for episode 4 shows her going wedding dress shopping.

With her mom Sharon and friend Katie in tow, Maci goes to a bridal salon to try on wedding dresses. While her 21-week baby bump is on full display, the attendant reveals Maci is planning to marry Taylor after welcoming baby No. 3, saying they will fit the dress to her liking after the birth. (Maci welcomed son Maverick Reed in May and reportedly plans to wed Taylor in October.)

Despite Maci’s plan to hold off on marrying until after she delivers, Katie makes it clear she thinks her bump looks good in the first wedding dress she tries on. “It’s even cute with your belly!” her friend comments. Maci agrees with a smile and so does the attendant, but Maci and her mom seems more concerned with the way the top of the dress looks.

When she goes back into the dressing room Maci announces she may have found the perfect dress. “We might have a game changer guys!” she excitedly tells her guests.

Of course, Maci won’t be the only star of episode 4. MTV has also released sneak peeks for Amber Portwood, Farrah Abraham and Catelynn Baltierra’s storylines.

As first teased in the synopsis for “Animal Instincts,” Farrah will get into a blowout fight with her boyfriend Simon during an Easter celebration. A sneak-peek clip shows the start of their argument with Farrah telling off her beau for walking inside her home with shoes on and not drinking wine her mother poured for him.

Elsewhere, Catelynn will welcome a new family member -- and no, we’re not talking about a baby! After her rough situation with her daughter Carly’s adoptive parents in episode 3, she’ll have something to smile about. Her clip shows her helping her new baby pig settle into her home.

Amber will face some drama in episode 4 when her daughter Leah accuses her of making “excuses” and not picking her up for one of her assigned visits. Amber makes it clear she was in the hospital when they were supposed to be together, but Leah says she can’t remember if her dad, Gary Shirley, told her that.

“Teen Mom OG” airs Mondays at 9 p.m. EDT on MTV.
