Justin Timberlake and Jessica Biel were met with a sudden and scary surprise at Paris Fashion Week. A man seemingly attempted to tackle the "SexyBack" singer as he and his wife arrived to the Louis Vuitton show. Photographers snapped the man hooking his arm around JT's ankle, catching the superstar couple understandably off guard. Justin and Jessica shook off the incident like total pros, though, continuing to stride into the Louvre hand-in-hand.
