Soap stalwarts Steve McFadden, Ross Kemp and Letitia Dean lead tributes to Barbara Windsor from her EastEnders co-stars.
The much-loved star, who suffered from dementia, died on Thursday evening at a London care home, husband Scott Mitchell said.
She was best known for the Carry On films and for her role as Queen Vic landlady Peggy Mitchell in EastEnders.
McFadden, who plays Windsor's on-screen son Phil Mitchell, said: "I truly loved Barbara and, like everyone, I am going to miss her terribly.
"When anyone ever asked what she was like, I would always say she was everything you would hope she would be, and more.
Ross Kemp, who played Windsor's other on-screen son Grant Mitchell, tweeted: "Dame Barbara Windsor, the woman who always had time for everybody, has sadly left us. I will miss Bar always.
"My thoughts are with her husband Scott, who could have done no more and who stayed strong for her to the very end."

Dean, who stars as Sharon Mitchell, said: "I would like to say what utterly heartbreaking news I woke up to this morning.
"They broke the mould when they made Dame Barbara Windsor, there will never be another like that incredible woman, everyone who met her loved her and she will be deeply missed.
"I would like to send everything I have to her amazing husband Scott, what a beautiful soul he is. My heart goes out to him and I just wish I could give him the biggest cuddle he has ever had. RIP dearest Barbara. You will be missed beyond measure."
Shane Richie, who played Alfie Moon on the Walford-based soap, said "I'm absolutely devastated as Barbara was a friend as well as my TV boss in the Queen Vic.
"We shared many a story in between filming - to amazement of situations (we found ourselves in) to laughter."
Adam Woodyatt, who plays Ian Beale, said: "I grew up watching 'Babs' in the Carry On films and for me to then work with her was a privilege and honour.
"I have so many happy memories and moments that I will always cherish, even when Peggy floored Ian with a punch.
"My thoughts are with her amazing husband Scott, her family and friends. Rest in peace Barbara."
Larry Lamb, who played Peggy's love interest Archie Mitchell, recalled the first time the pair met on the set of the BBC One soap.
"The reason I was there was because she decided she wanted a new man in her life in the show, and I was the one that got chosen," he told BBC Breakfast.
"And she just looked at me because she was such a tiny thing, I did not realise, and she said: 'You are tall, never mind darling, we're all the same height lying down.'
"She was larger than life. She was the head girl at EastEnders, she was the one everybody respected and she liked everything to run smoothly.
"She was an old-school actress... She knew how to keep everybody together and make it a team, she was really special."
He said she made her mark in the Carry On films as this "extraordinarily funny lady... very sexy, very funny, very alluring, very naughty."
Patsy Palmer, who played Bianca Jackson on EastEnders, wrote on Instagram: "We shared such magical times together and I'll cherish every one.
"I can hear that laugh now as I sit and think about her. I hope it'll ring in my ears forever. She always looked out for me."
Actress Danniella Westbrook, who played Windsor's on-screen daughter Sam Mitchell, tweeted: "My heart is broken. Bar you will always be in my heart forever."
Diane Parish, who plays Denise Fox in EastEnders, paid tribute: "Our dearest friend and colleague has passed and left a hole, not only on our screens, but in our nation that cannot be filled.
"I will remember her kindness and of course laughter.
"She made the special effort to spend time and say something meaningful to each and every person the last time we saw her at work. So sorry for her loss for you Scott.
"Little lady, Big presence. Sleep in peace Bar."
Lucy Benjamin, another of Windsor's former EastEnders co-stars, posted: "What a sad sad day. Rip my darlin Babs. You were a true star in every sense."
