The 31-year-old 'Crazy in Love' hitmaker, her sister Solange and mother Tina will be supporting 'Miss A Meal fundraising campaign', reported Contactmusic.
The initiative encourages supporters to miss a meal and donate the money they would have spent to the campaign.
"I was 13 and my sister Solange was eight when we started donating and serving meals to the homeless after church. We learned that we are all three pay cheques away from poverty. It was a lesson in humility for all of us," Beyonce said.
