I think the Backstreet Boys may have just found the opening act for their upcoming world tour. During The Ellen DeGeneres Show on Monday, the boy band made a surprise appearance to help Mary Poppins Returns star Emily Blunt get over her fear of singing in front of people. To help ease her nerves, the group sang their hit song song "I Want It That Way," and we can't get over how amazing Blunt sounds! In addition to her perfect harmonies with the band, she really steals the spotlight when she croons the song's final line. Even BSB was impressed! Might we suggest making the actress an honorary Backstreet Girl? See the amazing video ahead.
