All is bright with this couple! Jill Duggar spent Christmas Eve on Wednesday, Dec. 24, with Derick Dillard's side of the family, where the pregnant TLC star happily displayed her growing baby bump on Instagram.

"Great time with the Dillard relatives on Christmas Eve!" Jill wrote, alongside a sweet family snapshot with her in-laws. "#dillardfam #ChristmasEve #familytime."

In the photo, Jill wears a maxi skirt, sneakers, and a candy-cane striped shirt which envelopes her burgeoning baby bump. The proud future mom beams beside her husband, who wears a plaid button-down in the family portrait.

This is Jill's first holiday season as a wife, after she married Dillard this past June in Springdale, Ark. This past weekend, Derick took to Twitter to celebrate six months of being a husband.

The devout Christians revealed this past August that they were expecting their first child together, just 60 days after their wedding. "We really didn’t know how long we’d be able to keep it a secret with all of our friends. We wanted to tell them," Jill later told Us Weekly of disclosing her pregnancy news so early.

"Believing that life begins at conception and that every life is precious no matter how young, we would — even if there were to be a miscarriage — we would still want that child to be recognized," she told Us. "So it was something that we thought about and went forward with."

As for how her husband has been taking care of her throughout her pregnancy? "He is so good!" Jill beamed to Us about her husband. "He makes sure he gives me snacks before I get out of bed — protein snacks or saltines just so I’ll have something in my tummy before I start moving around. Grabbing me water…so he is so sweet. He is amazing… Married life is the best!"
