Someone got all dolled up for her latest TV appearance!

Nicole Richie stopped by Jimmy Kimmel Live on Thursday, and the 33-year-old reality star/fashion designer looked gorgeous in a long metallic gown. And those blonde locks? We're SO glad she ditched the colorful tresses and went back to a more natural hue!

Nic is currently promoting the second season of her VH1 show, Candidly Nicole, which premiered on Wednesday, and she's also been busy with her fashion lines. So what about those rumors that she's splitting from hubby Joel Madden? Though she ditched her wedding ring when she stepped out with the couple's two kids last week, she put it back on for her interview yesterday. If she was really about to end things with the Good Charlotte rocker, we doubt she'd still be wearing that band on her left hand...
