Earlier this week, reports surfaced – including one in In Touch Weekly – suggesting that the two women were getting ready to get back in front of the cameras together.
"They get along quite well and have a wicked sense of humor when they're together. Everyone keeps telling them they need to capture it on camera and now they've decided to," a TV insider reportedly told the mag.
But according to reps for both stars, the stories are fiction.
"Ridiculous," Rosie's rep told Access Hollywood. "[There's] no truth to it."
When asked if the rumors were true, Star's rep quipped, "Nope."
While the two may not be heading to reality, Rosie is charting a solo course to radio. She'll launch "Rosie Radio," a news and entertainment show on Sirius XM this fall.
She also is a recurring guest star on Lifetime's summer hit, "Drop Dead Diva."
