Local stars Longoria and Nelson, who both grew up in the state, were among the first to reach out to victims of the blast. Willie who was born and grew up 120 miles north of the state capital, in tiny Abbott, which is about five miles north of West. Wrote on his page, "West has been in my backyard all my life. My heart is praying for the community that we call home."

While the Desperate Housewives star, who hails from Corpus Christi tweeted, "Keeping the people of West, Texas in my thoughts and prayers,"

Singer Katy Perry added her thoughts on the disaster, writing, "Reading all the news about Texas. It's a very sad time for lots of ppl (people). Let's send extra love & light out. Don't take anything for granted."

Country singer Blake Shelton also took to the social networking site to write, "Man... Thinking about all my Texas family and friends tonight. I love y'all."
