Jennifer Lopez looked divine as she strolled the black carpet wearing a gorgeous Maria Lucia Hohan gown at the What to Expect When You're Expecting premiere. E!'s own Catt Sadler and Marc Malkin were on hand to chat up the film's stars, so of course they made sure to spend some time with J.Lo.
The American Idol mama dished on her beau Casper Smart, her ex Marc Anthony and even had some advice for the new hosts of that other singing competition…
So, how do Lopez and her dancer beau decide how to work the carpet at big events like this one?
"He just does what he wants to do," Lopez said. "He knows I'm working, and we just play it by ear. We don't try to plan it too much. It's a special occasion."
And speaking of working, Lopez dished on trying to find balance when it comes to work and family.
"It is just like any working mom's dilemma," the 42-year-old thesp said. "It's tough. It's a balancing act. You put them first and then you have all these other things that you have to do, that you have to give your time to as well, and you have to make sure that they're OK in the process."
One thing Lopez has appeared to find balance with is her relationship with her ex-husband Marc Anthony, with whom she cohosts the Spanish reality competition show, Q'Viva.
"[Marc and I] are gonna be performing together in Las Vegas with our whole Q'Viva crew," Lopez said. "Marc and I were friends for 10 years before we got married. We got married, we had two beautiful children, and we're still friends. Things disappointingly don't work out the way that you dream them in your mind sometimes. That's life. But, that doesn't mean that the caring goes away or the friendship or the things that brought you together disappear. They haven't for us, so we just want to be great parents and great friends and just try to do things well for them."
And before stepping away into the premiere, the American Idol judge offered a little bit of advice for new X Factor judges Britney Spears and Demi Lovato.
"Be yourself," Lopez said. "That's what I think every time I'm out there. Treat people how I want to be treated."
