Move over, Marge Simpson -- Jennifer Lopez is joining the mile-high club!

Or should we say the piled-high club?

At the April 28 Paris premiere of her new comedy "The Back-Up Plan," Lopez -- wearing a Lanvin leather dress and Salvatore Ferragamo heels -- got everyone buzzing with her gigantic beehive.

The mammoth mound is perhaps the most high-fashion look the mother of twins has worn while promoting her latest project, inspired no doubt by the models walking Lanvin's Spring 2010 runway, who wore a very similar hair style.

J.Lo played it safer at prior promotional events, with Old Hollywood loose waves and a silver one-shoulder Gianfranco Ferre dress for the film's April 21 L.A. premiere, and pulled-back locks and a Bottega Veneta grosgrain halter dress for the April 27 photo call in Madrid.

Whatever teasing 40-year-old Lopez may take for her bold beehive, it's unlikely it will sting -- the superstar, who has come a long way since her curly-haired days as a Fly Girl, was recently named Us Weekly's Style Icon of the Decade.

And besides, Lopez told Allure magazine in January, she's got an easygoing personality: "When you're a creative person, there's a certain carefree-ness about you that makes you want to ride in the convertible with the top down and your hair in the wind and all this stuff."

Maybe that's how she got the beehive?
