That's just one of the revelations in a frank Q&A with the pop diva in Newsweek magazine.
In addition to admitting that she confabs with the star of My Cousin Vinny, Houston, 35, straight-up addresses whispers that she and hubby Bobby Brown are courting drug habits.
"No, I'm not a drug addict, and neither is my husband," she says in the issue on stands today. "If that were so, you'd get a lot less work out of me."
As for why people think she's on drugs, the entertainer theorizes: "[W]ith people, it gotta be one thing or another. If we're not fighting or screwing around, then we're on drugs."
The way Houston tells it, stress, not drugs, is what ails her.
"When I'm stressed I don't eat, and I guess that makes people think I'm on drugs," she says, thereby becoming the second celebrity in as many months, after Ally McBeal star Calista Flockhart, to discuss her dietary habits in print.
Newsweek presses Houston on a scheduled Rosie O'Donnell Show guest appearance that she skipped last year--an incident that fueled drug rumors. The singer maintains that she was sick and (again) under stress. She says she worked out the issue with host O'Donnell, even if she adds: "But I don't hang with Rosie, and Rosie doesn't hang with me."
As for the home front, Houston says she and the oft-troubled Brown, her mate of six years, are fine.
"We have our ups and downs like anybody else," she tells the mag. "But it's about staying together. I'm Mrs. Bobby Brown and not the other way around. That's not going to change."
Houston's first non-soundtrack CD in eight years, My Love Is Your Love, is due in stores Tuesday.
