On Sunday, Ariana Grande's mom, Joan Grande, took to Twitter to share a message about the attack at her daughter's Manchester, England concert. The blast killed 22 people and injured more than 60.
"This past week I have spent in reflective thought, prayer & deep sorrow," she wrote.
"I stand with you all in the face of evil & we stand together to never let it rule our lives! Thank you to all those who helped in any way that night in Manchester. I continually thank those who are & were in service protecting our freedoms every day all over the world! #MemorialDay."
ABC News previously reported that Joan helped usher concert goers to safety after the blast.
