Topher Grace was the first tweet Kutcher responded to after the actor, who played lead character Eric Forman, eulogized Roberts on Twitter earlier on Monday.

"I was so sad to hear that Tanya Roberts has passed away. She was a Bond girl, one of Charlie's Angels, and truly a delightful person to work with. I had never acted before and, to be honest, a little nervous around her. But she couldn't have been kinder. We'll miss you Midge," Grace wrote alongside a photo of Roberts."yo bro she's not dead," Kutcher replied hours later after news broke.Grace then responded with a GIF of Kutcher's character Michael Kelso throwing his arms up in the air in celebration.Minutes later, Kutcher replied to costar Debra Jo Rupp, who had also mourned Roberts death on Twitter earlier in the day.

Rupp, who played Eric's mom Kitty Forman, shared a photo of herself with Roberts on the show.

"Tanya had a big deep hearty laugh. She was all instinct and beauty. In the first season of 70's we had a scene in the kitchen, drinking cocktails and laughing together. She laughed, spit her drink in my face, apologized profusely and did it 3 more times.I loved her. RIP beauty," Rupp wrote."dj she's still alive," Kutcher replied a few hours later.Rupp then copied Grace, sharing the same GIF of Kelso throwing his arms up in the air.
