Olivia Munn, Kristin Chenoweth and Carrie Underwood have offered heartfelt tributes after multiple tornadoes swept through Oklahoma on Friday (31May13), less than two weeks after a deadly twister devastated the state.

At least five people were killed when a series of tornadoes hit Oklahoma City and its suburb of Moore, which was previously torn apart on 20 May (13).

The storm system moved northeast on Saturday (01Jun13) as stars including Oklahoma natives Munn, Chenoweth and Underwood took to Twitter.com to reach out to fans affected by the natural disaster.

Munn tweeted, "Hope everyone is okay in Oklahoma... So sorry to the victims and their families of the tornadoes today. My thoughts and prayers are w/ (with) you all," while Chenoweth writes, "My native Oklahoma. I love you," and Underwood adds, "What on earth is up with this weather in Ok? Enough already! Praying everyone stays safe and sound..."

Seinfeld star Jason Alexander adds, "Sending love and funds again to Oklahoma. So sorry for your losses," rocker Slash writes, "Hoping for the best, for all the folks in Oklahoma City tonight," and Transformers' Josh Duhamel offers, "Praying for everyone's safety."

Country star Blake Shelton, who pulled in $6 million (£3.9 million) for the tornado relief effort in Oklahoma with a Tv fundraiser this week (beg27May13), also assured concerned followers his loved ones in the state are fine, tweeting, "For those asking all my family were safe again tonight. Pray for the ones who weren't as lucky..."
