Jennifer Aniston and Reese Witherspoon are arguably two of the biggest actresses in Hollywood -- and according to After Lately's Heather McDonald, they're also two of the most low-maintenance.

"It was great having Jen Aniston on the show. She's super sweet, has a really hot body, the good hair...and she's really, truly friends with Chelsea [Handler] so I think that's the main reason why she did it."

Witherspoon, 35 -- who played herself during season one of the semi-scripted E! series -- will make her second appearance on After Lately this winter.

"She's just as delightful as always. I tried to bond with her because we have kids the same age, so I think that's gonna work out," McDonald, 41, joked during a recent visit to Us Weekly's NYC offices. "I think we're gonna do some park stuff."

McDonald, a Chelsea Lately staff writer, adds that "we tried to get them in and out of there early, because it's E! and I don't think they were making any money at all. I think Chelsea's lunch from Katsuya was the only thing they got that day besides getting to, you know, be with us in a  scene."

Aniston, 42, and Witherspoon won't be the only A-list stars appearing on After Lately: Jane Fonda, Jay Leno and Sharon Osbourne have all filmed cameos for the show, which airs Sunday nights at 11 p.m. on E!.
