Sexy looks stole the spotlight this week.

Tennis superstar Serena Williams showed off her phenomenal figure on Wednesday, wearing a red hot Victoria Beckham dress and sparkly Christian Louboutin pumps during an appearance on the "Late Show With David Letterman."

Sanaa Lathan was also in the Big Apple this week and visited BET's "106 & Park" to talk about her role on the Starz series, "Boss." The actress wowed the crowd in a floral printed mini dress perfectly displaying her stunning stems.

Meanwhile out west in Hollywood, Nicole Richie stepped out at the Sunset Strip Music Festival in one of her own designs--a lasercut leather skirt from the star's Winter Kate collection. She paired the edgy piece with a black Mugler blouse, two-tone Jimmy Choo heels and added a pop of color with a bright yellow clutch.

Take a look at these ladies and the rest of the week's style standouts in the slideshow below.
