Holly Madison's 3-year-old daughter Rainbow Aurora is officially a big sister -- to her baby brother, Forest!
Madison revealed the name of her second child on Instagram on Friday, Forest Leonardo Antonio Rotella, after she and husband Pasquale Rotella welcomed the newest addition to their family on Sunday. The 36-year-old former Girls Next Door star is now resting at home.
"I'm so happy to be at home with a healthy baby boy, Forest Leonardo Antonio Rotella," Madison wrote on Friday, hugging a giant blue teddy bear. "Thank you for all the kind comments over the past few days."

Madison also took some time out on Thursday to wish her hubby a happy birthday. Madison and Rotella have been married since September 2013, after welcoming daughter Rainbow in March of that same year.
"Happy belated birthday to the best husband and dad," she Instagrammed alongside a smiling pic of the two.
ET chatted with Madison in May, when she shared the unique name Rainbow wanted to give her baby brother.
"The name she picked out was Strawberry, so I don't think I'll go with that!" she joked.

She also revealed that more kids are definitely in the future for her and Rotella.
"We'll see how this one behaves, but my husband wants a lot of kids, so we'll see," Madison revealed. "He's like, 'Let's have six!' ... We might end up adopting some because I don't know if I can push them all out."
