"Lost River" star Eva Mendes shared some relationship advice especially on how she keeps Ryan Gosling happy. The 41-year-old American actress, model, singer and designer also talked about baby Esmeralda, who already lets them sleep through the night at the age of six months.

In an interview with "Extra's" AJ Calloway, the new mom revealed that by not considering "sweatpants" when at home, she has been keeping her partner Ryan Gosling happy about their relationship.

She claimed that it is her secret rule.

"You can't do sweatpants... ladies, number one cause of divorce in America, sweatpants, no!" the "Lost River" star exclaimed.

Meanwhile, the gorgeous partner of the 34-year-old Canadian actor said she's lucky that she's getting some sleep already during the past days. However, this is still not as much as Eva Mendes would like to enjoy each night.

"But you never know, right, something random can happen and she's just suddenly not sleeping through the night and you're like, wait, I thought we were sleeping through the night, what's up?!" she confessed.

"Why does it always happen at three or four in the morning?!" Eva Mendes added about having baby Esmeralda.

When asked about how she immediately regain her striking figure, Ryan Reynolds' partner emphasized that there was actually no secret to getting back in shape a few months after giving birth to baby Esmeralda.

Eva Mendes instead credited others for helping her look her best.

"You're helped in those situations, I want women at home to know, you're lit, you're angled, so yes, it was a few months after the baby, but with a lot of help," she said.

With her new CIRCA makeup line called "Walgreens," the "Ghost Rider" leading lady is helping women feel better about themselves.

"This is an amazing opportunity for me to bring quality products to people at drugstore prices," Eva Mendes said.

"My must-have now... we have this magic hour concealer which is really helpful these days for me, I'm not getting much sleep," Ryan Gosling's partner added.
