George Clooney was back on the Italian set of his Mercedes Benz commercial this afternoon. George was also spotted filming the ad on Monday, though this time he was dressed up in a suit for the cameras. George lounged at a café table and hopped on a motorcycle for the shoot in Milan, which isn't far from his home in Lake Como. He's been spending most of the Summer at the lakeside getaway. George has played host to multiple visiting friends lately, with pal Karen Duffy joining him on his boat and Stacy Keibler's friends Jenna Dewan and Channing Tatum also making a trip to the vacation spot.
