John Legend to perform for birthday girl Hillary Clinton

John Legend will perform at Hillary Clinton's birthday party later this month (Oct 15).

The All Of Me singer is set to entertain guests at the star studded bash to mark 2016 presidential candidate Hillary turning 68 years old.

John is sure to have everyone on their feet at the event, with Hillary promising that even she might show off some dance moves.

"Some women don't like to discuss their ages, but I think that on your birthday, you should live it up!" Hillary writes on the party invite, according to People.com. "This year, I'm excited to celebrate the fact that I'm running to be the youngest woman ever to be President of the United States."

The event, to be held in New York on 25 October (15), one day before Hillary's actual birthday, will also serve as something of a fundraiser for her campaign.

Tickets to the party range in price from $250 to $2700, with all proceeds going to the campaign.

The party will be one of the first for John since he announced that he and wife Chrissy Teigen are expecting a baby.

The pair had made no secret of their struggles to fall pregnant, and Chrissy broke their happy news on Instagram.

"John and I are so happy to announce that we are pregnant :)," she wrote on Instagram Monday 12 October (15). "As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family. We're so excited that it's finally happening. Thank you for all your love and well wishes. I look forward to all the belly touching! Xx"

John previously revealed his desire to start a family. But he joked that Chrissy had said he lacked enough masculinity to manage a boy, and would be more suited to having daughters.

"Chrissy thinks I'm not athletic enough to have a boy," John told DuJour magazine back in May (15). "I'm a musician, I'm good with women, and I'm a feminist, so I think I'll be a good 'girl daddy.'"
