Teen Mom Cheyenne Floyd, Zach Davis and kids Ryder, 4, and Ace, 7 months, wear matching pajamas in Christmas Eve photo

TEEN Mom star Cheyenne Floyd, fiancé Zach Davis and kids Ryder, four, and Ace, seven months, dressed up in matching pajamas for their adorable family Christmas eve photo.

The couple got engaged in April.

The MTV star shared the sweet family snap on her Instagram Story.

In the photo, she, Zach, and the children wore matching tan pajamas.

The outfits appeared to have words written on them in white, though it's unclear what they said.

Cheyenne, 29, and her family smiled as they posed in front of their Christmas tree and a pile of presents.

The photo features a sticker that read "Merry Christmas eve eve," a reference from the TV show Friends.

Cheyenne shared two other family photos the same day, this time on her account

In those photos, the family of four posed in matching black shirts.

Cheyenne held Ace on her lap in the , while Zach held Ryder.

The parents switched children in the second photo.

The Teen Mom star captioned the post: "Happy Holidays" and received many holiday wishes from followers.

Leah Messer responded with "Happy Holidays" and a heart.

Gary Shirley, meanwhile, responded to the post: "Beautiful family."

Cheyenne and Zach are parents to Ace, whom they welcomed in May.

She shares Ryder with Cory Wharton.

STEPPING UP

Although Ryder is not his biological child, Zach has been a supportive step-parent.

Recently, he inked his love for his step-daughter on his hand.

Zach debuted a tattoo of Ryder's face via Instagram.

He also got her name tattooed alongside the portrait.

Cheyenne was first to share the tattoo on social media.

She gushed: "My fiancé tattooed his bonus daughter's portrait today."

She added: "I am so blessed to have a man that not only loves me but loves my daughter as his own."

Fans couldn't get enough of the display.

One commented: "Seriously crying omg."

A second Instagram user gushed: "Omg that so beautiful! I'm crying. To see a man to love your baby as his own is beautiful. That how it should be. You got a real one... One we all pray for! God bless you."

Another user echoed the sentiment, writing: "That's a beautiful expression of love and to show Ryder that she's just as much a part of his heart as you and Ace are."

Zach has never shied away from grand gestures for Ryder.

RYDER'S RING

In another show of dedication to his step-daughter, Zach presented her with a diamond ring when he proposed to Cheyenne in April.

Zach popped the question during their teddy-bear themed baby shower.

Cheyenne shared an Instagram Story from the special day, writing: "Still not over that he got both me and Ryder rings. He knows this is a package deal."

The couple has been busy planning their wedding and building their dream home since.
