JT and His Social Network Costars Get Silly on Spanish TV and Look Dapper in London

Justin Timberlake joked around and tested out some science experiments with his The Social Network costars on a Spanish TV show yesterday before heading to London for a photo call this morning. The cast has spent the week in Europe premiering the very hyped movie, which took the top spot at the box office in America last weekend. JT plays the cofounder of Napster in the flick but revealed in a new interview that he personally prefers records to MP3s when he listens to his favorite songs. While Justin is putting his own music career on hold for now to focus on his many film roles, he took a break from the promotion circuit over the weekend to indulge his passion for fashion at the Givenchy runway show in Paris.
