Ellen Pompeo is downplaying the rumors about Katherine Heigl returning to "Grey's Anatomy."

The actress stopped by "Chelsea Lately" (weekdays, 11 p.m. EST on E!) to promote the ABC medical drama. When she wasn't talking tequila and making out on camera, Pompeo was shooting down the rumors that her former co-star Heigl seemingly started while promoting her film "One For the Money."

"So wait, what's going on? Is Katherine Heigl coming back to the show?" Handler asked Pompeo.

"I don't think so," Pompeo said, shaking her head.

Handler pressed further and Pompeo said, "No, I don't think that's happening."

During her January press tour, Heigl said she was ready to return to "Grey's Anatomy," and told the powers that be at the series that she wants to come back.

"I really, really, really want to see where [Izzie] is," Heigl told E! "I just want to know what happened to her and where she went and what she's doing now."

Pompeo's comments come as Season 8 of "Grey's Anatomy" -- and her contract with the show -- come to a close. Both Pompeo and co-star Patrick Dempsey have been vocal about their desire to remain with the series, while remaining vague.

"I would never turn up my nose at 'Grey's' ... If I hear from the fans that they want us to keep going, then I would continue because we owe them everything," Pompeo told TV Guide in October.
