Check out Mother Monster's message to Mama Finlay:
God bless you and your mama and family, we'll all be praying @taylorswift13 💐- Lady Gaga (@ladygaga) April 10, 2015
"The results came in, and I'm saddened to tell you that my mom has been diagnosed with cancer," Taylor posted on Tumblr the other day. "I'd like to keep the details of her condition and treatment plans private, but she wanted you to know."
Gaga wasn't the only one to tweet her support. Tons of fans did, too. Shortly after her announcement, #PrayForMamaSwift began trending on Twitter, with fans sending missives of love to Taylor and her mom.
