Update on Aug. 30: This story has been updated to add more stories of celebrity donations from both Texas natives and those outside the Lone Star State.

As the world reels from the devastation from Hurricane Harvey in Houston and surrounding areas, celebrities from around Texas -- and the nation at large -- are using their money and their megaphones to offer help to those affected.

Sometimes it might feel as if Beyonce has transcended one single location, but she still calls Houston "home." She sent a statement to the Houston Chronicle on Monday saying, "My heart goes out to my hometown, Houston, and I remain in constant prayer for those affected and for the rescuers who have been so brave and determined to do so much to help. I am working closely with my team at BeyGOOD as well as my pastor (Rudy Rasmus at St. John's in downtown Houston) to implement a plan to help as many as we can."

Olympic gold medalist and native Texan Simone Biles has been volunteering her time and energy to help with the recovery effort. She and her family live north of Houston, in Spring. She has been seen working alongside members of the Arlington Police Department at a distribution center in Conroe.

From closer to Dallas, Irving-raised Bachelor star Sean Lowe went to Houston and hopped in a boat. "Today I had the chance to do what I could to help some people in the Houston area," he said on Instagram, where he posted several photos of very-flooded streets. "I couldn't believe the devastation. My heart broke for all the elderly who are immobile and the mothers trapped in their homes with young babies. But I was encouraged by the selflessness of so many Texans who came to help where they could. Definitely a day I'll never forget."
