Enrique Iglesias recently faced his harshest critics yet: his twin babies. The 43-year-old singer shared an adorable video of his 8-month-old twins, Nicholas and Lucy, giggling in their stroller as he ran back and forth making silly noises. The best part, however, comes when one of the twins fears it's over and a visible look of distress comes across his face. In his caption, Enrique wrote, "Tough audience to entertain." If you find yourself squealing at the video, then please enjoy Enrique and Anna Kournikova's cutest pictures with their twins so far.
