"Full House" stars and friends John Stamos and Dave Coulier 's bond is as strong as ever. This was made apparent after Coulier revealed on Wednesday he had been diagnosed with stage 3 non-Hodgkin lymphoma, reports People.

John Stamos showed love to his “brother” Dave Coulier on Instagram Wednesday after Coulier, 65, announced that he’s been diagnosed with stage 3 cancer. Stamos, 61, posted a tribute with various photos of the pair over the years, as well as an emotional message to his longtime friend.

As an additional tidbit for Full House fans that isn’t quite so downbeat: Dave Coulier revealed in the latest episode of Full House Rewind that he now has a new co-host in the form of fellow sitcom vet Marla Sokoloff, who famously portrayed Gia Mahan on both the mothership series and its follow-up.
