Beyonce, Katy Perry at US inauguration

US President Barack Obama's inauguration is shaping up to be an event as star-studded as any red carpet, with performers including Kelly Clarkson, Beyonce, Katy Perry, Stevie Wonder, Alicia Keys, Usher, Mana and Brad Paisley.

Beyonce will sing the national anthem and James Taylor will sing "America the Beautiful" on the West Front of the Capitol on Monday.

Both performers are regular Obama supporters, and celebrities have been a big part of Obama's strategy to attract voters.

Bruce Springsteen is a regular supporter, as are Lena Dunham, Scarlett Johansson, Jay-Z and dozens of others.

Pop-rock trio fun., who had a wild year with two No 1 hits, a near-platinum album and six Grammy nominations, will perform for first lady Michelle Obama, Sasha and Malia and Jill Biden on Saturday at the Kids' Inaugural Ball.

"It's been amazing year, and 2013 is kicking off with us doing the inauguration ... it's just an incredible thing," said lead singer Nate Ruess.

"I think the three of us care so much about Obama and so to be invited, I can't even deal."

Fun. will be joined at the concert by Perry, Wonder, Keys, Usher, Smokey Robinson, Paisley, Marc Anthony, Mindless Behavior, Nick Cannon and the cast of Glee.

"I think they're all very talented people. Stevie's my brother and so is Usher," Robinson said in an interview.

"I know Katy ... I'm very happy to be performing among them."

While there will be no shortage of star power, it's not quite a repeat of the 2009 inauguration when everyone who's anyone flocked to Washington DC for a televised concert on the Mall.

The first time around, Beyonce was a surprise guest, singing the Etta James classic At Last for the first dance.

Her husband, Jay-Z, was another surprise at the private staff ball, singing 99 Problems but George Bush Ain't One.

The Jonas Brothers - then favourites of the Obama girls - performed at the kids' concert and U2, Springsteen and so many ot! hers performed on the Mall.

There may still be surprises in store, but plenty of performances are assured.

Keys, Paisley, Chris Cornell, Jamie Foxx, Jennifer Hudson and Anthony will perform at the Commander-in-Chief's Ball on Monday.
