It isn't easy being Chelsea Handler's celebrity BFF -- just ask Jennifer Aniston.
Aniston's biggest gripe with the best-selling author, however, has to do with Handler's hygiene. "When we were in Cabo, she never showered," Aniston recalls. "She would be like, 'What? I went in the pool.' It's gross!"
The Wanderlust star says she and Handler's other A-list pal, Reese Witherspoon, "can only take her in small doses," adding that "it's getting tough" to be seen with her in public.
The season finale of After Lately airs Sunday at 11 p.m. EST on the E! Network.
