Halloween's a family affair when it comes to the Teen Moms and their kiddos! Many of the MTV stars got into the spooky spirit for 2015 and celebrated the holiday with festive costumes. 

Teen Mom 2 star Jenelle Evans spent the day with her boys Jace and Kaiser, who had a fun hay ride in their North Carolina neighborhood with a group of pals, including Evans' new boyfriend, David Eason. 

Jace is a red ninja with some friends. ???????????? #happyhalloween2015

Jace, 6, was a sporty red ninja while Kaiser, 16 months, went all out as The Nightmare Before Christmas' Jack Skellington. 

"He wouldn't sit still for makeup. Kaiser's Halloween costume!!!" Evans captioned one photo of her tiny tot in his black and white pinstriped ensemble. "Amazing. Kaiser looks like beetle juice tho lol."

Later in the evening, Evans got into the Halloween spirit herself wearing a pearl-covered bra and blue bottoms with fish scales. The mother of two posed with her pal Tori, writing, "Mermaid and Army girl. #happyhalloween2015 @babyvickk Costumes by @fashionnova."

In South Dakota, her costar Chelsea Houska also enjoyed some festivities, but opted to make her costume theme one for the whole family. She and her daughter Aubree, 5, both dressed as Wonder Woman, while her live-in boyfriend, Cole DeBoer, wore a Superman getup.

"#superfamily @coledeboer," Houska captioned one sweet photo of the trio. 

She later posted a sweet photo dancing with her boyfriend of more than a year, writing, "I love this man."

Across the country, Farrah Abraham and her boyfriend, Simon Saran, attended the "Day of the Killer Costumes" party in Las Vegas at Ghostbar Dayclub at Palms Casino Resort. She dressed as the Queen of Hearts and he rocked a Batman costume. 

And though she was apart from her daughter Sophia, 6, she still took the time to share three photos of her little girl in different costumes. 

"Sophia wants your help which #halloween2015 costume should Sophia #trickortreat in tonight??," she captioned the photos of her daughter as an old lady, a vampire, and a spooky ghost. 

Abraham's nemesis Maci Bookout didn't post any Halloween pics, but her son Bentley, 7, went out with his dad, Ryan Edwards. The Tennessee-based dad got into the trick-or-treating, painting his face to look like a skeleton, while his son appeared to be dressed like a Jedi. 

Happy Halloween!!! ????

Amber Portwood's daughter Leah, 6, dressed as a racoon and spent the day with her dad, Gary Shirley, and her half-sister, Emilee, who wore a cat costume. 

Leah Messer, who recently lost a custody battle to her ex-husband Corey Simms, still got to take her girls out for Halloween. On Oct. 30, they attended the school's party. Aleeah, 5, and Leah's younger daughter Addie, 2, whom she shares with ex-husband Jeremy Calvert, both appeared to be dressed as Elsa from Frozen, and Ali, 5, also wore a costume, but it was covered as she posed behind her sisters.
