Jennifer Lopez's Poopy Pool

Ah, the joys of parenting!

Potty training is a struggle for a lot of parents, and it sounds as though Jennifer Lopez and her husband Marc Anthony are no exception! During an appearance on The Late Show with David Letterman this week Marc explained how the pair ended up with a $6,000 bill following a potty training disaster with their 3-year-old son.

"[Max] had an accident in the pool and it got into the filter system and they charged us to clean it," Marc revealed. "That was expensive. He took a $6,000 dump in the pool."

Despite the expensive setback, the potty plan - which involves rewards for Max and his twin sister Emme - remains in "full force," J.Lo's hubby says.

"Every time they use their potty we give them a lollipop. Then a few days passed and we ran out of lollipops. I'm like 'You should probably get them checked out if they're using the potty that much.'"
