Emily Blunt Gets a Backstreet Boys Surprise for an Unexpected Duet

“Mary Poppins” star Emily Blunt admitted she still has a fear of singing in front of people, so Ellen pushed her to face her fears by taking the stage. Luckily, the Backstreet Boys made a surprise appearance to help her out and sing their classic hit, “I Want It That Way.” #EmilyBlunt #BackstreetBoys #MaryPoppins
