Did someone say 2001? Britney Spears takes a trip in the Red Carpet Time Machine, landing back in Dolce & Gabbana on Sunday’s Grammy Awards red carpet. The star arrived in a sexy, see-through Dolce & Gabbana lace dress over a bodysuit that reminds us of a classic Brit-Brit style moment — her sheer black lace dress over a bra top and hot pants at the 2001 VMAS, also by Dolce & Gabbana. It may be nine years later, but we have to say that Britney looks as good as ever — we’re even digging the dark brunette hair she’s rocking. Tell us: What do you think of Britney’s deja-vu look?

On the heels of last weekend’s Hope for Haiti telethon, stars continue to rally for the relief effort, this time opening up their closets for the cause. Britney Spears will be auctioning off one of the two shimmery silver Versace dresses she wore to the MTV Video Music Awards in 2008—which might even be a good luck charm, given that was the same night she made her comeback performance after her public meltdown and took home three wins in the process. Details as to the specific dress and charity have yet to be released. And she’s not the only star who’s opening her closet to benefit the earthquake-stricken country.

–Kate Bosworth is putting the diaphanous, size-2 pleated halter dress by Chloe she wore to the Food Bank of New York City’s annual Can-Do awards gala last year up for grabs, with proceeds benefitting OxFam International’s Haiti Relief Program through the Charitybuzz Heal Haiti Charity Auction (to place a bid, visit charitybuzz.com).

–Susan Sarandon is getting in on the action by donating the sultry size-6 Dolce & Gabanna LBD she wore to the 15th Annual Critics’ Choice Movie Awards on January 15 at charityfolks.com. Proceeds from the sale, organized by Modelinia.com and ping pong parlor SPiN New York (of which Sarandon is a co-owner), will benefit Friends of the Orphans in Haiti.

–Artists for Peace and Justice are helping Meryl Streep, Josh Brolin, Gerard Butler, Amy Poehler, and Olivia Wilde donate their outfits worn at the 67th Annual Golden Globe Awards through an eBay auction. Find out more details at artistsforpeaceandjustice.com.

–And while Lady Gaga is holding onto her outrageous costumes, the performance artist/pop singer is selling Lady Gaga Haiti Relief T-shirts on her website, ladygaga.shop.bravadousa.com. To spread the news, she Tweeted, “Buy Gaga merch today. 100% of profit goes to earthquake relief. Little Monsters save the world today!” –reporting by K.C. Baker and Ken Lee

She did it again! After months as a blonde, Britney Spears has traded her flaxen tresses for a raven color. And while hair changes are nothing new to the star, who has notoriously sported everything from her signature baby blonde to, well, no hair at all — we always love seeing her change up her look. Tell us: Should Britney keep walking on the dark side in the new year, or go back to blonde? –Katherine Kluznik Rentmeester
