Jennifer Lopez Flawless Again At Premiere of ‘What to Expect When You’re Expecting’ (PHOTOS)

J.Lo's Men!
Jennifer Lopez's romantic timeline.
Once again, Jennifer Lopez knocked it way, way way out of the park at last night’s premiere of What to Expect When You’re Expecting in Los Angeles.

The 42-year-old singer-actress-American Idol judge wowed the crowd in a stunning nude dress by Maria Lucia Hohan that teased her cleavage.

How did her dress compare to her Idol looks?

Still, despite the cleavage tease, the dress was a bit more of a conservative look for J-Lo, who on American Idol has been testing the the waters — not to mention the length of her seams — each week on the show. (See her best Idol fashions in our gallery below!)

Also in attendance at the star-studded premiere: J-Lo’s 25-year-old boyfriend, Casper Smart, who worked the red carpet in sunglasses and a tie-less suit.

In a recent interview, J-Lo — who has two twins, Max and Emme, with ex-husband Marc Anthony — revealed she is open to adopting a child.
