Following Monday's historic tornado that devastated the Oklahoma City area, there has been an outpouring of support from public figures, celebrities, and everyday Americans. President Barack Obama addressed the nation from the White House Tuesday morning, expressing his severe concern and promising federal aid for the victims and families. As search and rescue teams scour the disaster grounds, celebrities have also been taking advantage of social media to share thoughts, prayers, and words of encouragement. Oklahoma natives Olivia Munn and Carrie Underwood gave personal accounts and hopes for fellow Oklahomans, as did Kristen Chenoweth, who also asked her followers to donate to the American Red Cross and Humane Society relief efforts.

Justin Timberlake and Jimmy Fallon kept the party going at the Time 100 Gala in NYC last night. The two friends, who were named two of the magazine's 100 most influential people in the world this year, were joined by Justin's wife, a Tom Ford-clad Jessica Biel, and a Lanvin-wearing Claire Danes. Also out were honorees Lena Dunham and Vice President Joe Biden, who took the chance to work the room of Hollywood stars. Other guests included Amy Poehler, Steven Spielberg, Daniel Day-Lewis, and Christina Aguilera, who performed at the event and hobnobbed with Lena on the red carpet.

Inside the bash, the stars wasted no time celebrating the honorees. Justin and Jimmy danced around the room and goofed off with Amy and musician Frank Ocean. Lena commented on getting on the Time 100 list, saying that the first person she told about being on the list was her father. She said, "I called my dad because he was a layout editor at Time in the 1970s, so I was super psyched, and I wanted to tell him that I was making good in his former institution. I heard there was a drinks cart when he worked there." Meanwhile, Daniel, who picked up the best actor award at this year's Oscars, commented that he is "more than mildly astonished" that he landed on the list.

The annual Time 100 Gala inspired another round of red carpet glamour, with Jessica Biel and Olivia Munn leading the star-studded pack. And what better occasion to dress to the nines than in honor of some of the world's most influential people? With Biel in black, head-to-toe Tom Ford, Munn in bright canary-yellow Michael Kors, and Claire Danes in a more exotic Lanvin look, the night played host to a spectrum of black-tie ensembles. Lena Dunham wore a shimmery number from Saint Laurent's much-discussed Saint Laurent Fall '13 collection and Christina Aguilera went the siren route in formfitting Victoria Beckham.

The carpet wasn't the only thing that was red tonight. Some of our favorite actresses — and nominees — arrived at the Academy Awards in the eye-catching hue. Both Sally Field and Jennifer Aniston reached for Valentino dresses; Field opted for a long-sleeved number with semisheer panels, while Aniston decided on a timeless princess-gown silhouette. Not to be outdone, Olivia Munn and Marcia Gay Harden went for body-con gowns, also in the standout color. One thing's for sure: these ladies certainly painted Hollywood's biggest night red.

For last night's Vanity Fair and Juicy Couture Vanities Calendar party in West Hollywood, the styles proved fun and flirty, and they certainly favored leg-baring numbers. Olivia Munn, who also shared hostessing duties, stepped out in a navy-and-white tuxedo-inspired minidress by Bird, and paired the look with a Juicy Couture clutch and peep-toe pumps. Meanwhile, bold prints took center stage thanks to Jaime King's Alexander McQueen dress and Brooklyn Decker's matching top and skirt set from Preen's Spring '13 collection. Eva Longoria opted not to walk the red carpet — and worked a casual outfit inside — while Kate Mara, Ellie Kemper, and Minka Kelly turned out even more cool cocktail ensembles.
