Who's Upset Over Beyoncé Singing At Inauguration?

Beyonce is scheduled to sing at President Obama's inauguration, but some are up in arms over the pop diva taking center stage at the event. INSIDE EDITION explains.

Who would want to ban Beyonce from the president's inauguration? After all, she famously sang the Etta James classic, "At Last" during the Obama's first inaugural dance in 2009.

Now, the superstar is going to sing the national anthem at this year's inauguration. But some of Obama's supporters want the pop superstar to be disinvited. They've started a petition on the White House's "We The People" website.

Health and fitness activisits, who are big supporters of the first lady's Let's Move! campaign say Beyoncé's $50 million Pepsi sponsorship doesn't exactly mesh with the healthy-living movement.

Activist Laurie David, ex-wife of comedian Larry David, explained her position in a Huffington Post column.

"Are we really going to help the children of our nation lead healthy lives, or not? If we are, we'll have to stop pretending it's a good idea to give the new face of Pepsi, aka Beyoncé, the honor of singing our national anthem."

The White House promptly responded to the anti-Beyoncé petition by deleting it from its website, pointing out that it's up to the inaugural committee to pick entertainers.

Meanwhile, Oprah Winfrey, fresh off her Lance Armstrong interview, is not going to the inauguration.

A rep for Oprah says she'll be overseas making several speeches over inaugural week.
