Holly Madison is pregnant! The 36-year-old TV personality, who is best known for being on the reality series "The Girls Next Door," is expecting her second child with husband Pasquale Rotella, People Magazine confirmed.

Rotella also announced the exciting news on Friday via Instagram, posting a video of his wife's sonogram. He captioned the post, "Blessed and excited to announce @hollymadison & I have a baby owl on the way! can't wait to welcome another beautiful soul into our family & watch #rainbowaurorarotella become a big sister! #hollymadison,"

The former Playboy model is three months along with the pregnancy and is due in August. Madison told People Magazine that she doesn't know the gender of her baby yet, is "kind of feeling the boy vibe."

Holly and Pasquale are already parents to two-year-old daughter Rainbow Aurora, who was born in March 2013.

"She was the first person my husband and I told," Madison told People Magazine about her daughter who is secretly hoping for a sister. "She's rooting for a girl. I think she's going to be a good big sister. She's very caring and she loves playing with her baby dolls and taking care of the pets."

The soon-to-be mother of two said she's excited to be expecting again, adding, "This time I know what to expect a little bit more. [That] makes it even more enjoyable!"

Last Wednesday, the former E! star showed off a small baby bump while attending the opening of Jennifer Lopez's new show "All I Have" at Planet Hollywood Resort & Casino in Las Vegas. Madison wore a black embellished dress

Holly and Pasquale married in September 2013 in Disneyland after dating for two years, and five years after she ended her relationship with Playboy founder Hugh Hefner. Madison talks about her relationship with Hefner in her memoir "Down the Rabbit Hole," which is being made into a TV movie.
