To prepare for her co-hosting stint on "The Ellen DeGeneres Show," Jennifer Aniston sought a little help from her friends...err, make that "Friends."

The actress reunited with two of her former co-stars for a segment promoting her appearance on the show Wednesday.

In the video, Aniston drops by Matthew Perry's home and asks him for advice, since he's also co-hosted alongside Ellen DeGeneres.

But the visit doesn't exactly go as planned -- turns out, the two haven't stayed in touch since "Friends" went off the air. An uneasy-looking Perry tells her she should have called before stopping by.

"We used to walk into each other's apartments all the time," Aniston argues. "I mean, we're friends!"

"That was a TV show, we haven't actually seen each other in a pretty long time, like eight years," he retorts.

As they're talking, Courteney Cox emerges from the home, trying to make an early-morning exit. "You're sleeping with her, too?!" Cox exclaims.

But she wasn't the only one hanging at Perry's house -- Portia de Rossi is seen trying to slip out the door, followed by DeGeneres herself.
