Carrie Underwood put on a show-stopping performance at a World AIDS Day event in Times Square on Monday night.
The country singer, who is expecting her first child with husband Mike Fisher, took to the stage sporting her burgeoning baby bump and belted out a set which included her new baptism-themed single "Something in the Water."
The event, which also featured other acclaimed artists such as Bruce Springsteen and Kanye West, was held to support (RED), an organization that aims to raise HIV awareness and ultimately end AIDS.
Iconic band U2 was originally scheduled to perform, however; they were forced to cancel as lead singer Bono is still recovering from serious injuries he sustained in a bike accident last month.
"Friends have stepped in to save U2's surprise World AIDS Day (RED) performance, which was jeopardized by Bono's November 16th bike accident in Central Park," the band wrote on their Facebook page.
"Adam Clayton, The Edge and Larry Mullen Jr. will be joined by Bruce Springsteen and Coldplay's Chris Martin, each of whom will take a turn as frontman on the U2 songs. Appearing at the personal invitation of U2, Springsteen and Martin have graciously donated their time and talents to save the World AIDS Day event from cancellation," they added.
At one point during the event, Underwood, who first hit the music scene with her 2005 debut single "Jesus Take the Wheel," smiled and waved at the crowd while standing alongside some of the biggest names in music.
In Oct., her powerful new single soared to the top of the Billboard Hot Christian Songs chart.
Former U.S. President Bill Clinton also made an appearance while lending his voice to the great cause. He took to Twitter shortly after the event to thank each performer.
"Proud to join @RED @U2 @coldplay @springsteen @kanyewest @carrieunderwood in NYC tonight. We can all act to #endAIDS," Clinton tweeted to his 2 million followers.
Bono, who has spent years campaigning to help end AIDS in Africa, said the special event was an opportunity to honor the U.S., which has played a key role in helping millions of HIV infected patients around the world access life-saving treatment.
"We wouldn't be at this point without American leadership, people from the left and the right," he said in a statement. "Today, 13 million people have access to life-saving treatment, up from 300,000 just over ten years ago. Americans don't know the role they've played in this fight. Tonight's event is to inform them and thank them."
