From NYC to LA, the red carpets were overflowing on Thursday, as stars stepped out in the best, worst and wackiest fashions.

Jennifer Lopez and Marc Anthony teamed up to announce their plans to launch two exclusive lifestyle brands at Kohl’s Department Stores, hitting The London Hotel in Los Angeles dressed to thrill. Jennifer rocked an ultra-glam, gold-belted Gucci frock with Gucci python heels, finishing the look off with Neil Lane diamond and gold cuffs and rings.

David Arquette has clearly been going through a rough patch in his marriage with Courteney Cox, as the two recently announced their separation. And what happens when a man takes some time away from his fashionable significant other? He ends up hitting the clubs in Hollywood every night, dressed in clown-like duds! David hit the town with a little pal of his, wearing a LOVE tank top from his Propr collection, with a single suspender across his right shoulder.
