Pete Davidson, who doesn't have a Twitter account, asked his friend and "King of Staten Island" writer Dave Sirus to share a touching message on his behalf.

"I don't have social media so I asked Dave to post this for me," the "Saturday Night Live" star wrote. "Just wanted you guys to know that Bob Saget was one of the nicest men on the planet. When I was younger and several times throughout our friendship, he helped me get through some rough mental health stuff."

Andy Cohen also paid a tribute to Saget and wrote, "He had the biggest heart and wore it on his sleeve. He was so generous with his feelings. A mensch. #BobSaget."

"The Hangover" star Ken Jeong posted a touching message for the late star, adding that he was in tears while typing it out. "Everyone loved him in the community. EVERYONE," he wrote.

In tears typing this, he was that genuine and the world should know that. Love you @bobsaget."

"Community" star Joel McHale also penned a heartfelt tribute for Saget, noting, "I'm so shocked at @bobsaget's passing. One of the most kind & thoughtful people I've ever come across & he just happened to be one of the funniest on the planet. I will miss you so much Bob. Love you dear friend. I'm so sorry @kellyrizzo. And so sorry to the rest of the family."

Josh Gad, who voiced Olaf in the popular movie "Frozen," tweeted, "There wasn't a kinder person in Hollywood than Bob Saget. I am having trouble wrapping my head around this. I do not want to believe this. It's all too much to handle."

Kat Dennings, Saget's co-star in "Raising Dad," too had some nice things to say about the actor.

"I was his TV daughter for one season and he was always so kind and protective. So so sorry for his family," she tweeted.
