Rihanna Shares White House Tour Photos

Pop star Rihanna may not be in line for the role of Barack Obama's spokesperson, but she looks quite at home behind the briefing room podium.

She posted the image of her trying to fill Josh Earnest's shoes during a recent stop at the White House.

The Stay singer is in the nation's capital for a free Veterans Day concert featuring some of the biggest names in music.

Rihanna, with her entourage in tow, took a tour of the President's mansion on Monday.

"West Wing Posse!!" she wrote along with one of the images posted on her Instagram account.

Rihanna was one of several big name acts performing at the Concert for Valor on Tuesday night on Washington's National Mall.

She was joined by Bruce Springsteen, Eminem and Metallica, among others.

The free concert was spearheaded by Starbucks president Howard Schultz to raise awareness for veterans' issues.
