John Stamos went on Twitter Monday morning and tweeted aboutBob Saget’s death.

Stamos wrote: “I am broken. I am gutted. I am in complete and utter shock.”

He continued, “I will never ever have another friend like him. I love you so much Bobby.”

One Twitter user responded to his tweet: “stay strong john. we’ll forever remember danny & jessie ❤️”

Another added: “Like many, you were my first thought because the love you had for each other was apparent. So sorry for your loss.”

Stamos and Saget were co-stars on the hit ‘90s sitcom, “Full House.”

They were brothers-in-law on the show, and share a brotherly bond off-screen.

Saget died in his hotel room in Orlando, Florida.

He was found unresponsive on Sunday.
