For the first time since she announced her pregnancy on September 1, singer Carrie Underwood wore her baby bump proudly onstage at the Global Citizen Festival on Saturday, September 27. The event is on its third year and aims to end extreme poverty by 2030. It was held in Central Park in New York City.

Underwood performed the song “Everybody Hurts” by R.E.M. wearing a short, black ensemble that only slightly concealed her growing baby bump. DailyMail reported that Underwood worked the stage, singing and engaging the crowd with lots of energy. Underwood apparently performed in front of 48,000 people alongside the likes of DJ Tiesto, Jay Z and The Roots.

The day before the Global Citizen Festival, Underwood made a guest appearance on the Today show and spoke about her pregnancy as well as her musical projects. Underwood revealed the novel way in which the festival gave away free tickets to the concert, which was to require people to sign up for acts of community service through the website www.globalcitizen.org.

When host Hoda Kotb asked her how she was dealing with the prospect of being a mother, Underwood replied, “It’s still kind of weird to be honest. Sometimes I’ll be with my husband and I’ll be like, ‘I’m going to be a mom and you’re going to be a dad. Is this real life?’ But we’re really excited.” Underwood is married to hockey player Mike Fisher, who is also the father of her baby.

Underwood added that she would try to model herself after her mother, whom she said was “wonderful.”

She also talked about her new single “Something In The Water,” which was also released on September 29. The song is part of her upcoming album titled Greatest Hits: Decade #1 and was co-written by Chris DeStefano and Brett James.

“It’s really kind of a joyous, uplifting song about changing your life for the better and kind of having that ‘a-ha’ moment, to waking up and your life being different from that moment forward,” Underwood said on Today last Friday.
