Jennifer Aniston rocked a black leather minidress this morning for a London photo call on behalf of Horrible Bosses. She had her main men from the movie by her side, including Kevin Spacey, Jason Bateman, Jason Sudeikis, and Charlie Day. Jennifer and the guys recently did press for the film back home in the States, including a junket in NYC and a premiere in LA. Jason, Charlie, and Jason said Jennifer will shock fans with her raunchy role — playing against type is one of the reasons the movie did so well at the US box office. The Horrible Bosses reviews were great, too, and now fans will see if Jen can repeat her success in Europe. Jennifer has spent time between movie duties with her main man Justin Theroux. He shaved and dressed up to attend Jennifer's Walk of Fame ceremony last month, and it seems his love of leather may even have inspired her ensemble today.
