Alec Baldwin and his 30 Rock co-stars have led tributes to late funnywoman Jan Hooks following her death on Thursday (09Oct14).

The former Saturday Night Live (Snl) star passed away aged 57, and her loss has sent a shockwave through Hollywood.

Her last Tv appearance was in 2010 on fellow Snl alum Tina Fey's hit comedy 30 Rock, and castmembers including Baldwin have offered their condolences.

In a post on Twitter.com, Baldwin writes, "I'm sad to learn that we lost Jan Hooks, a remarkably sweet and talented actress..."

Cheyenne Jackson, who also worked with Hooks on the hit sitcom adds, "RIP JanHooks. Worked briefly with her on 30 Rock and she was a twistedly brilliant comedic presence."

Hooks also made a series of appearances on 1990s Tv comedy 3rd Rock from the Sun, and castmember Kristen Johnston writes, "I can't believe it. Jan Hooks appeared in many 3rd Rock eps (episodes). We all truly loved her. I can't believe she's gone, another comedic genius."

Fellow former Snl star Amy Poehler adds, "Jan Hooks was an incredibly talented and lovely person. She will be dearly missed," while actor/comedian Kevin Nealon, who dated Hooks in the 1980s, writes, "My girlfriend in the 80s and my friend forever, Janners. God, were you talented. Too soon and too sad. #JanHooks."

Other tributes have come in from stars including Judd Apatow, Seth MACFarlane, Dane Cook, Patton Oswalt and Seth Meyers.
