Jeff Ross is paying tribute to his late friend, Bob Saget.

Bob Saget should have been celebrating his birthday on Tuesday, May 17.

Unfortunately, he passed away suddenly in January.

Ross paid tribute to his late friend on Twitter.

“Happy birthday Bob,” he wrote.

“Wherever you are I hope you are celebrating with pastrami and martinis,” he added.

He attached a photo of Bob Saget holding balloons in one snap.

In the other snap, the two are standing side by side.

Widow Kelly Rizzo also paid tribute to her late husband on Instagram.
