Lauren Conrad posed in a black jumpsuit at Cotton's 24 Hour Runway Show in South Beach in Miami yesterday. She was joined by Louise Roe and Giuliana Rancic for the event, which kicked off last night at 8 p.m. and continued until this morning. Giuliana, in a Tibi dress, hosted with husband Bill as 1440 cotton looks went down the runway in the 24-hour time period. Lauren landed in Miami on Thursday, showing off her newly blonder locks at the airport.

Josh Hartnett got in on the pre-Oscars parties when he dropped by the Vanity Fair and Fiat party benefiting the United Nations International Labour Organization in LA last night. The star-studded event, which was hosted by Ron Howard and composer Hans Zimmer, also included Lake Bell, Alyssa Milano, and Adrien Brody as guests. Josh had a busy evening, as he also visited the Hollywood Domino and Bovet 1822 event in West Hollywood. Alyssa — who wore Gucci to last night's event — will likely have a lot more Academy Awards-related events to attend this weekend, since her husband, David Bugliari, reps Bradley Cooper, who is nominated for best actor. Bradley has a lot of events on his plate this week, including Wednesday night's Vanity Fair dinner for Silver Linings Playbook, which he attended alongside costar Jennifer Lawrence and director David O. Russell. Don't forget to join us for our LIVE Oscars viewing party and red carpet coverage on Sunday, Feb. 24 at 5:30 p.m. EST/2:30 p.m. PST.

Julianne Hough, Fergie, and Hailee Steinfeld, in a Mary Katrantzou skirt, stepped out in LA last night for Elle magazine and the Sundance Channel's premiere of editor Joe Zee's show, All on the Line With Joe Zee, at Soho House. The bash gave Julianne a chance to catch up with her Safe Haven costar Josh Duhamel, who attended with wife Fergie. Joe's new show is the latest stylish reality show. In each episode, he acts as a mentor to a designer struggling to get their line off the ground.

We spoke with Joe Zee to talk All on the Line well before the program's debut on the Sundance Channel — the first episode actually airs tomorrow at 9 p.m. ET. He said, "It's not the typical portrayal of fashion; it's something that feels real, genuine, and authentic. I was so moved emotionally. There were times when I was on the floor with [the designers], jacket off, sleeves rolled up trying to help. There were also times when I was so mad at the designers, and there were other times when I wanted to hug them. I was so invested in their final outcome."

There's a cool new pant in Hollywood, and it comes in various shapes, sizes, and shades of green.

Many more stars are feeling green pants at the moment, so check them all out, then shop your favorites to wear with all your Summer pieces, including white blazers, crochet tops, and strappy sandals.

Michelle Williams was the belle of a private ball last night at LA's Chateau Marmont. The company Forevermark threw her the bash in honor of her Oscar nomination in the category of best actress, and her closest friend Busy Philipps was on hand for the occasion. It was the latest evening out on the town for Busy, who spent Wednesday at a Dior dinner with Halle Berry, Anne Hathaway, and more. Michelle was decked out in a short purple dress for the party, though we're most excited to see what she wears on Sunday after her 2006 Vera Wang pick ranked among the most iconic Academy Award gowns. Other stars like Bryce Dallas Howard, John Stamos, and Gina Gershon turned out to toast Michelle, who's sure to be a hot commodity at pre-Oscars events in the run-up to the big show.
