Celebrities and friends are mourning the news about Bob Saget's sudden death.

The Full House star's body was found in a room at the Ritz-Carlton in Orlando, Fla. yesterday (Jan. 9).

The Orange County Sheriff's Office confirmed that Saget was identified and pronounced dead on the scene. No signs of foul play or drug use were detected.

In the hours after the news broke, many of the actor's former cast mates shared their grief. Saget's Full House family opened up about the loss in a flurry of messages and painful statements.

Sisters Mary-Kate and Ashley Olsen (who played Saget's youngest daughter Michelle Tanner) released a statement about their TV dad via People.

"Bob was the most loving, compassionate and generous man," the sisters said. "We are deeply saddened that he is no longer with us but know that he will continue to be by our side to guide us as gracefully as he always has."

Candace Cameron Bure (who played D.J. Tanner, Saget's oldest daughter on Full House) opened up on Twitter: "I have no words," she wrote. "Bob was one of the best humans beings I’ve ever known in my life. I loved him so much."

John Stamos and Dave Coulier, who played Saget's best friends Jesse Katsopolis and Joey Gladstone respectively, were some of the first to comment.

"I am broken. I am gutted.  I am in complete and utter shock," Stamos tweeted. "I will never ever have another friend like him. I love you so much Bobby."

"My heart is broken. I love you, Bob. Your forever brother," Coulier wrote.

Kimmy Gibbler actress Andrea Barber shared her thoughts on Instagram.

"This one hurts," she wrote. "He had the biggest heart of anyone in Hollywood. He gave the biggest hugs. I am gutted that I will never be able to hug him again. Bob ended every text, every interaction with 'Love you.' Didn’t matter how long or short we’d been apart. He loved so deeply and so fiercely. And he never hesitated to tell you just how much you meant to him. This is the greatest lesson I learned from Bob Saget - don’t hesitate to tell people you love them. I feel at peace knowing that Bob knew exactly how much I adore him."

But Saget's Full House co-stars are not alone. Many of the comedian's peers and other famous co-workers have shared messages of their own.

Kat Dennings reflected on her Raising Dad co-star. "I was his TV daughter for one season and he was always so kind and protective," she wrote.

Others who commented on the loss include Whoopi Goldberg, Tim Allen, Josh Gad and Kathy Griffin.

Many recognized Saget's status as America's Dad after his years-long run as Danny Tanner on Full House and the Netflix revival Fuller House. Others simply commented on his undeniable spirit and kindness.

Below is just a sample of the outpouring of love for the late star.
