Celebrities are talking to ET about the widespread swine flu outbreak. Actress Lisa Rinna says she thinks her family may have contracted the virus prior to knowing what the swine flu was.

"I believe we all, except for myself, had the swine flu at our house," Lisa tells ET about her ill family. "How do you know it's the swine flu? I don't know but we had all the symptoms."

"We had it before it came out. ...We had it at our house, I believe, and everyone is fine," the actress explained to ET at the LG Rumorous Night with Heidi Klum event on Tuesday.

Hugh Jackman, whose 'X-Men Origins: Wolverine' movie premiere in Mexico was delayed, didn't seem too concerned about the swine flu. "I'm not really changing anything for me," the actor said at the Los Angeles premiere of his film.

Other stars talked to ET about what they're doing to prevent the swine flu including: Ryan Reynolds, Kelsey Grammer, Vanessa Williams and other "Ugly Betty" cast members.
