Jessica Biel's backside is putting J.Lo's to shame these days.

While Jessica has always sported a rockin' bod, she's apparently been working her gluteus to the maximus and it shows.

But make no mistake, unlike the title of her latest film "The Illusionist," Biel's booty is no mirage. And from the looks of her recent outings, it seems the former "7th Heaven" star isn't afraid to show off those dangerous curves either - and we couldn't be happier.

Check out Jessica in all her newfound bootylicious glory.
