In his tweet, Carrey shares a quote from his "brilliant teacher and friend" Jeff Foster about a concept called "deep rest." The actor also expressed his respect for Grande, saying, "I admire your openness" and, "I feel blessed to have such a gifted admirer."
"I can’t process this or breathe hold on," the 25-year-old songstress tweeted upon seeing his response.

"I don’t think u understand how much i adore u or what u mean to me. thank u for taking the time to share this w me," she said. "I can’t wait to tattoo this tweet to my forehead."
