It's Maci Bookout!
Maci Bookout loves spending quality time with her main man, 4-year-old Bentley.
"Pete showed up last night. Sneaky little elf!" the Teen Mom star tweeted, along with this adorable photo.
It won't be long before Santa shows up at the Bookout abode too. Good thing Bentley's been good all year!
