Olivia Munn Heartbroken Over Oklahoma Tornado Tragedy

Actress Olivia Munn has reached out to a family in her native Oklahoma after learning their two little boys died in the state's recent tornado disaster.

Severe weather struck America's southern states, including Texas, Oklahoma and Kansas, earlier this week (beg23May11) - just days after a powerful twister claimed more than 120 lives and devastated whole neighbourhoods in Joplin, Missouri.

Munn, who was born in Oklahoma, has been watching the tragedy unfold on the news and on Thursday (26May11) took to her Twitter.com page to urge fans to help locate Ryan Hamil, a three-year-old boy who went missing during the storms.

The Date Night star was left devastated after learning the youngster and his 15-month-old brother Cole both died in the disaster.

In a series of posts on Twitter, Munn writes, "My thoughts/prayers with tornado victims. My heart goes out to the Hamil family in Oklahoma.. Their 2 little boys didn't survive the tornado. So sad. My hope & lots of good thoughts & wishes are w/the (with the) people affected by the tornadoes.... Big hug."
