John Legend says his longtime friend, Kanye West, is in need of some rest.
While promoting the Dec. 2 release of his new album, Darkness and Light, the 37-year-old R&B singer told ET's Nischelle Turner that he hasn't spoken to the rapper since he canceled the rest of his Saint Pablo U.S. tour after he went on a bizarre rant and left the stage early during his Sacramento, California, show.
"I'm not gonna speak out of term and speak for him," Legend said on Monday afternoon before news broke that West was hospitalized.
"All I can see is what [West] said to the public -- and that is he's tired and needs some rest," he noted, referring to the tour cancellation.
Last month, Kim Kardashian West was robbed at gunpoint while asleep in her hotel room in Paris, France, and Legend thinks what happened to West's wife has most certainly impacted him. "I think he's been through a lot lately with what happened to Kim," he said. "I think if he needs to rest, I think his fans will be patient and let him rest. He'll come back stronger, hopefully."
As for his friendship with West, Legend added, "He's the one that signed me, he's the one that helped discover me and help me get a record deal. I wouldn't be where I am now without him. I am very grateful to him."
Kim was expected to make her first red carpet appearance on Monday night at the Angel Ball in New York City, but was not in attendance. Her sisters Khloe and Kourtney Kardashian were at the event, along with their mother, Kris Jenner, who spoke to ET about West's well-being.
"I think he’s exhausted. Just really tired," Jenner said of her son-in-law. "It’s a grueling tour."
