Hostin had two children with her husband, Emmanuel Hostin. Their 17-year-old daughter Paloma joined the TV host during an episode of The View last May.

“That beautiful girl you’re seeing is Paloma Hostin, Sunny’s daughter,” co-host Joy Behar said as Paloma joined to close out the show.

The 17-year-old competed in the Junior Olympics last year and received support from both her mother and brother. Gabriel showed up to support his sister.

“She was terrified — it was really really crowded… My son showed up that morning because she said she needed him. He flew in to just support her,” Hostin said, according to People.
