Baby on board!

Courtney Stodden took to Instagram on Monday to show off her growing belly in a very Courtney Stodden way, stripping down to a very revealing two-piece for a risque dance.

In the clip, the reality TV star is seen gyrating to The Temptations' classic "Ain't Too Proud to Beg" in a too-small two-piece, Stodden sporting a smiley face drawn on her teeny bump.

"Embracing these insane body changes with a smile lol #pregnant #babybump," the 21-year-old wife of Doug Hutchison, 56, captioned the video.

The video comes on the heels of Courtney's vow renewal with her husband of 5 years earlier this month. The two tied the knot in 2011, when she was just 16.

"Renewing my vows to the man I love under the Hollywood sign was an honor. The first reason why we chose that location for such a special moment is because Hollywood ultimately brought us together," Stodden told toofab of the ceremony. "I wouldn't have even known my hubby if it wasn't for this town!"

"The second reason is due to the fact that Daeida 'Ida' Hartell, 'The Mother of Hollywood,' married Harvey Henderson Wilcox, a man over 30 years her senior when she was just a teenager," she continued. "Together, they founded Hollywood and Ida originated its name. We feel a connection to such a power-couple!"

We're glad to see Courtney is feeling better about her pregnancy ... especially after posting this just last week:

When does this end? 😷 #firsttrimester #baby #pregnant #morningsickness #notjustinthemornings
