Leah Remini Is Not Accepting Jennifer Lopez's 10 Day Eating Challenge

Girlfriends Leah Remini and Jennifer Lopez are thick as thieves. But there are some things Leah won't do when J Lo asks. The star publicly denied her friend's challenge to join her and beau, Alex Rodriguez's 10 day no carb, no sugar diet. Keep reading for all the details.

Jennifer challenged three people on Instagram to tag along on the health kick: Leah, Hoda Kotb and movie producer Elaine Goldsmith Thomas.

Leah shot her girl down hard! “No, I’m not up for it,” she wrote under the singer's video. “Gonna go eat now…maybe a plate of pasta, some cookies, but you all enjoy.”

Meanwhile, Hoda was all in! She announced her acceptance on the Today show. “I think if y’all are my friends, which I think you are, we should all do this together,” she said to coworkers Savannah Guthrie, Carson Daly, Craig Melvin and Al Roker.

While the morning show host's cohorts weren't thrilled, the group agreed but only if they could still drink their coffee for their early morning wake-up call. Today's Instagram account then made it official commenting under Jennifer's video, "We're ready! ???."

Mario Lopez weighed in on the fun, too! The Extra host commented, "Get it!" on Jennifer's post.

A Rod also challenged three pals. The fit couple was three days into their own trial when they called for their friends to get on board!
