WASHINGTON (CNN) - It's unlikely President Obama will stop by, but for Hollywood fans the Ibiza nightclub is the hottest ticket in Washington tonight.
A star-studded group strolled the heated red carpet at the Recording Industry Association of America's post-inaugural bash.
Rihanna, who was slated to perform, told CNN's Jessica Yellin that during her travels abroad she'd found tremendous excitement about Obama's election.
"It had such a strong impact all over the world," she said. "The first black president, and being part of that was such a big deal to the rest of the world."
Colombian singer Shakira couldn't vote in the presidential election, but is still an ardent fan of Obama's. She gushed that she "can't be objective" about the 44th president - she just likes him too much.
Other celebrity Obama fans who turned out included Leonardo Di Caprio, Cher, Courtney Cox and David Arquette, Roseanna Arquette, Tobey Maguire, and Josh Groban.
Groban said he was inspired by the president's call to action - as long as it didn't include basketball.
"I'm going to have to work on my game," he said.
The function was a benefit for Feeding America, a hunger-relief charity.
