Expecting: The contestants reveal their baby bumps on stage at the pregnancy pageant in Houston, Texas
Beauty pageants are usually reserved for slim and single women years away from starting a family.
But these mothers-to-be in Houston, Texas, have shown that not all expectant moms want to be at home with their feet up in their final months of pregnancy.
The pregnant women got their kit off to proudly show of their burgeoning bumps, dancing, gyrating and even doing the splits on stage.
