Jennifer Aniston " a notorious chainsmoker " is thisclose to signing a big bucks deal with Nike. No word on what she'll be shilling (her own line? something that already exists?), but she will reportedly earn "the largest sum ever paid by the sportswear company for a celebrity endorsement." One of her ads could also nab a spot during the 2007 Super Bowl.And for those folks who were going to rag her for being greedy, the article also says that she'll donate a large part of her salary to a cancer charity. Hmmm... Maybe Jen's money will go to cancer research, scientists will find a cure of lung cancer and then it totally won't be weird that a chainsmoker is the new face of a line of athletic wear.
