Although our cheap television thrills may come in the form of Gossip Girl, The City and The Hills, when it comes to feeling clever, there's nothing we like more than Mad Men and 30 Rock. So imagine our utter joy when we heard that Mad Men's Don Draper, the delicious Jon Hamm, has a three episode cameo playing Liz Lemon's 30 Rock love interest! Not since the cross pollination of brand Beckham and Ugly Betty have we been so excited about a cameo. Although we may have to wait a while for it to air in the UK (we'll keep you posted on that one), the US date for Hamm's first appearance is 5th February. Almost in time for Valentine's day! What better treat could we ask for?
