These 'Momo Twins' are the cutest babies ever

(FOX 11) - Double the trouble certainly means double the cute in this case.

These adorable six-month-old twins with the chubbiest cheeks have stolen our hearts. The Instagram account @leialauren posts photos of them in matching outfits, known as the "Momo Twins."

They got their nickname because they are monoamniotic-monochorionic twins, meaning the twins are identical twins and develop in a single, shared a placenta and amniotic sac in their mother's womb.

According to About Health, only about 1 percent of twins develop this way.

They are just too cute.
