They may be past their trick-or-treating prime, but the Bush twins couldn’t pass up candy and a good cause Thursday night.
Jenna Hager and Barbara Bush, both 28, joined celebs like former New York Giants running back Tiki Barber and girlfriend Traci Johnson for a masquerade ball for UNICEF, which celebrated the 60th anniversary of its trick-or-treating program.
Jenna paid homage to the roaring twenties with a flapper ensemble, while her sister got in touch with her dark side in a head-to-toe black angel costume.
UNICEF is a children’s rights organization, which raises funds to provide children in need with medicine, nutrition and education.
