Co-host Raven-Symone jokingly threw her hands in the air and got out of her seat upon hearing the American Idol judge's reaction to the pic.
Whoopi Goldberg also teased Lopez about her comment. "Do you need us to show you what chunky looks like?" she quipped. "This a little bit on the chunky side, okay Jennifer? This is not the chunky side," Goldberg added, pointing to herself and then the selfie.
Lopez -- who is currently doing a residency in Las Vegas -- clarified that her weight does "fluctuate" based on her performance schedule. "When I'm doing the show, I go down, I get slim, and then when I stop, I'm eating -- and I get chunky," she added. "Not chunky, but you feel it for a dancer."
The "Booty" singer does have a rigorous workout schedule that keeps her from packing on too many pounds. "I love to run. I still enjoy it, but right now because of the Las Vegas show, dancing is a big part of my workout and cardio," she explained. "I do low impact cardio because it's so much dancing."
Lopez also revealed to ET her number one beauty secret. "Sleep is very important," she shared. "I get my seven to eight hours sleep no matter what."
