Doris Roberts and Eva Longoria Doris Roberts and Eva Longoria

Eva Longoria and Doris Roberts have been neighbors in the Hollywood Hills for years, and on an April episode of Desperate Housewives, the two will finally work together. I ran in to Doris at the opening of Mamma Mia! at Hollywood's Pantages Theatre (the production runs through April 8), and the Everybody Loves Raymond vet told me she had a blast on the Housewives set.

"I play a very rich woman who hires Gaby as her personal shopper," says Doris, 81, of her character, also named Doris. "Her husband dies — he was very rich, but very cheap and didn't let her spend any money. Now she's out to spend a lot of money. Gaby's husband is with an organization that takes care of homeless addicts, so he tries to get money from my character, which he does. But then I find out they're ripping me off and I let them have it!"

Doris is also keeping busy with a new sitcom pilot for ABC called Counter Culture, about three aging sisters. "It's great," she says. "Delta Burke, Ken Howard and Wink Martindale are also in it. It's about a bunch of lovely ladies in Texas who run a coffee shop."

She also had fun seeing Mamma Mia! "I love Mamma Mia!," she raves. "To sit in the audience, laugh and have a good time is what I like!"
