Here's a look at all the fashionable stars in this week's "Best Style Moments" roundup...
Mariah Carey turned heads in a lace mini dress while attending the "American Idol" finalists party in Los Angeles Thursday night. Looks like she's been sticking to her Jenny Craig weight loss regimen or has on a might tight pair of Spanx. Either way, we think she looked fab.
Ooo la la, Ciara! The singer stepped out in a stunning black Givenchy dress for the French design house's Fall 2013 presentation during Paris Fashion Week. Ciara's blunt cut blonde hair is the perfect contrast to the moody look. And we're thrilled she's learned that she can be just as sexy without showing too much skin.
We've seen a bunch of celebrities rocking Marc Jacob's popular striped sequin pieces from his Resort 2013 collection (see: Alicia Keys and Sopia Coppola), but we think NeNe Leakes pulled it off the best.
"The Real Housewives of Atlanta" and "The New Normal" star stopped by "Watch What Happens Live" this week in her sparkly getup and we were mesmerized. We hardly even noticed her bestie, Cynthia Bailey, sitting beside her in a gold lamé gown and sky-high afro. Yes, NeNe's outfit was that good!
Check out those lovely ladies and the rest of the style stars including--Rihanna, Miss USA Nana Meriwether and Melanie Fiona--in the slideshow below.
