Holly Madison and husband Pasquale Rotella have welcomed their second child.
The couple are already parents to 3-year-old daughter Rainbow.
"What an incredible week. A crazy, stressful start, which transformed into this magical moment," Rotella wrote.
"First, a five-year-long indictment against me was finally dismissed; then yesterday Holly, Rainbow & I welcomed a healthy 8-pound, 14-ounce boy to the family. Now I'm holding my beautiful son at the hospital reading amazing birthday wishes from all of you," the 42-year-old event promoter added.
Rotella was given three years probation and a fine last week after striking a plea bargain over bribery and embezzlement charges.Madison followed her husband's announcement by sharing a photo of the new baby holding her finger.
Madison, the ex-girlfriend of Playboy founder Hugh Hefner and a former "The Girls Next Door" star, welcomed Rainbow in 2013 and married Rotella the same year.
"I'm so excited," the star told People in March.
"[Rainbow] was the first person my husband and I told ... 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."
