Roberts' last public outing came less than a month ago when she walked the red carpet at the premiere of Casa Valentina at the Pasadena Playhouse in Pasadena, California.

A source tells ET that the actress had dinner with friends last Monday night where Roberts seemed in high spirits, laughing, eating and even singing "Moon River" with the group at a friend's home. Those close to Roberts are "numb" following the news of her death, the source added.

Roberts began acting in the '50s and went on to appear in movies like National Lampoon's Christmas Vacation and Grandma's Boy, a number of Broadway productions and on television, most notably starring in Raymond for nearly a decade.

Ray Romano, who played Roberts' son on the beloved CBS sitcom, spoke out about her death, telling ET in a statement, "Doris Roberts had an energy and a spirit that amazed me. She never stopped. Whether working professionally or with her many charities, or just nurturing and mentoring a green young comic trying to make it as an actor, she did everything with such a grand love for life and people and I will miss her dearly."

Patricia Heaton, who played Roberts' daughter-in-law in the series, called her death "truly the end of an era.”

"Doris Roberts was a consummate professional from whom I learned so much," Heaton wrote on Twitter. "She was funny and tough and loved life, living it to the fullest. Nothing gave her greater joy than her three wonderful grandchildren, of whom she was so proud. It truly was a privilege, Doris. I love you and miss you."

Fellow Raymond co-star Brad Garrett also paid tribute to his TV mother, telling ET in a statement, "I am deeply saddened by the passing of Doris Roberts, an amazing lady and brilliant actor. Doris was vibrant and full of life both on and off the stage, and I am so grateful we shared so many wonderful memories. I will miss her greatly and will always remember her incredible kindness, humor, talent and heart."

While Everybody Loves Raymond creator Phil Rosenthal tweeted, "We loved our mom, the great #DorisRoberts. A wonderful, funny, indelible actress and friend."

Romano had recently teased a cast reunion at the ATX Television Festival in June. Sadly, that reunion will now be without both Barone parents, as Peter Boyle died in 2006.
