As her season of Teen Mom draws to a close, Maci Bookout is trying to make amends with her ex -- and father of her son, Bentley -- Ryan Edwards.
In the above preview clip from Tuesday's episode, Bookout, 21, asks her son to call his dad to invite Edwards (with his new girlfriend Dalis Connell) to Bentley's 3rd birthday party that night. Edwards agrees, but as Bookout hints, the visit doesn't necessarily go off without a hitch.
"Bentley's birthday was pretty emotional in dealing with the custody stuff with Ryan," Bookout tells Us Weekly ahead of her penultimate Teen Mom episode. "Birthdays and holidays are the hardest because we have to share him."
When she can't be with her boy on those milestone days, Bookout takes comfort that her son has a female influence in his life -- thanks to Edwards' new girlfriend, Dalis Connell.
"I'm a fan of her -- she's a really good girl. She's responsible and really good with Bentley," Bookout tells Us of Connell. "I know [she and Ryan are] on and off a little bit and that's aggravating because I don't know what Bentley's exposed to, but besides that, I'm rooting for her. I hope Ryan doesn't screw this up!"
Watch Bookout plan Bentley's birthday in the clip above before the full episode of Teen Mom airs Tuesday at 10 p.m. (EST) on MTV.
