While Britney Spears’ various costumes were no doubt being tributed last night at various Halloween parties across the country, it was the pop star’s songbook that was honored on The Sing-Off. Competing group Pentatonix performed an a cappella medley to Ms. Spears, mashing up her singles “Oops!… I Did It Again”, “Toxic” and “Hold It Against Me”. (We especially love the group’s dubstep breakdown during the latter.) Watch below, and if you dressed up like Britney for Halloween, don’t forget to enter our costume contest!
