The singer has long been one of the President's most high profile supporters.

She wrote a letter of praise for him ahead of last November's US presidential election, in which she credited him with inspiring the future generation, including her own daughter. 

She wrote: 'Every day we see your heart and character, inspiring us to give more of ourselves. You are the leader to take us from where we are to where we need to be. 

'You are the reason my daughter and nephew will grow up knowing that they can truly be ANYTHING they want to be.

Joining Beyonce at the state event was felow singer Kelly Clarkson, who tweeted a picture of the pair together.

'Me and B just hangin' out ....don't worry about it,' she wrote. 'Seriously, God did good. She is so beautiful!'

Kelly once said she was a fan of Republican presidential candidate Ron Paul, but she says she voted for Obama twice.

'I think it's going to be the coolest thing ever to look back with my grandkids and go: "I was a part of that and I'm proud of that. I'm not ashamed of that,"' Clarkson said in a recent interview.
