Best Dressed: Week of April 4, 2008

Jennifer Lopez's little black dress, plus Jaslene, Cameron and Gisele!

1. Best Worst 04.03.08 01 Lopez

Jennifer Lopez takes a break from double diaper duty to attend the New York premiere of Shine a Light, looking chic in a Reem Acra cocktail dress and sparkly pumps.

2. Best Worst 04.03.08 02

Jaslene Gonzales goes uber-glam in a violet off-the-shoulder gown, dangling earrings and updo at Tyra Banks'< 1st Annual Fierce Awards for America<'s Next Top Model.

3. Best Worst 04.03.08 03 Cameron

Cameron Diaz shows off her gams in a splashy-print Missoni dress and white wedge sandals by Christian Louboutin at the Kids' Choice Awards, where the actress picked up the Wannabe prize.

4. Best Worst 04.03.08 04 Mariah

Even in her least revealing outfits, Mariah Carey still manages to heat things up in a low-cut striped tank, black miniskirt and tights while in London to promote her upcoming album, E=MC².

5. Best Worst 04.03.08 05 Bundchen

Could Gisele Bundchen's dress be any more skintight? The supermodel rocked a slinky white dress that only she could pull off at the Ibiza launch party for Vogue Eyewear's new line.

6. Best Worst 04.03.08 06 Fergie

We're not loving the proportions or the pattern-clashes in the outfit Fergie wore to The Beatles Revolution Lounge at The Mirage…but gaudy and Vegas do go hand in hand, so maybe she's on to something!

7. Best Worst 04.03.08 07 Candela

Telemundo host Candela Ferro looks comfortable yet girly on the red carpet of an ATP event celebrating Latinos in Tennis, wearing a wispy ivory-and-black dress and t-strap sandals.

8. Best Worst 04.03.08 08 America

América Ferrera is predictably cute in a shimmery gold David Meister dress at the Nickelodeon Kids' Choice Awards, but we wish she'd start throwing a little more excitement into her style!

9. Best Worst 04.03.08 09 Moreno

Catalina Sandino Moreno plays it low-key in a roomy top, skinny grey jeans and suede booties for a special screening of 21 at the IFC Center in Manhattan.

10. Best Worst 04.03.08 10 Perez

Even though Rosie Perez commits two major fashion faux pas--visible bra straps and an air cast!--at the Behind the Lens Award event honoring Spike Lee, we still love her.
