Holly Madison
is one proud mama!

The"Girls Next Door" alum took to Instagram to share a sweet pic of her adorable daughter Rainbow.

"Swim time! #rainbowaurorarotella," she captioned the cute candid. 

In the photo, the blue-eyed beauty is standing in a bright pink Minnie Mouse hooded towel, drying off after a day at the pool. She's even posing just like the Disney character!

The former reality star recently posted another pic of her little one, posing in matching Burberry trench coats as they arrived in Amsterdam. 

So cute!

Madison is clearly loving life with Rainbow, so is she ready to add to her brood?

"Just having [Rainbow] is enough!" she told In Touch. "We really want to give her a sibling, but I need a little time. We'll start to think about it next year."
