The 35-year-old singer, who is in residency in the Planet Hollywood Resort & Casino, pledged $1m of the ticket sales of her Piece of Me show to the Nevada Childhood Cancer Foundation’s Britney Spears Campus.
Saturday, the mother-of-two opened the facility at the official opening saying: "I’m just really excited to be standing here for our new NCCF campus. We started fundraising in 2014 and we’ve raised one million to build this amazing facility to support the kids and the families everywhere. I’m so thankful to everyone for their generosity in making this a reality and making this happen."
