Eva Mendes says sweatpants are 'number one' cause of divorce

LOS ANGELES, March 19 (UPI) -- New mom Eva Mendes is not one to wear sweatpants.

While speaking about her new cosmetic line for Walgreens, CIRCA, with Extra, the 41-year-old actress revealed why she refuses to slip into the comfortable bottoms.

"No, no, you can't do sweatpants," Mendes said. "Ladies, number one cause of divorce in America is sweatpants. No, you can't do that."

The Place Beyond the Pines actress, who welcomed her first daughter with Ryan Gosling in September, defined her style as "feminine" before dishing on parenthood.

"I'm actually starting to sleep so I'm at a good place," she said. "Sleeping through the night, but every night is like, you never know. Something random can happen and it just suddenly is not sleeping through the night and you're just like, 'Wait, I thought we were sleeping through the night. What's up?' Why does it always happen at three or four in the morning?"

Mendes says that her new role has made her very appreciative of her own mother.

"My mother has never gotten more like 'I love you so much Mommy' texts," she revealed.

Mendes and Gosling have been dating on and off since 2011. The private couple was last seen together during a date night in January.
