Anna Nicole Smith has become a "guinea-pig" for diet company TrimSpa's new chocolate treat in a bid to lose weight after giving birth to baby DANNIELYNN. The former model, the longtime face of TrimSpa's diet pills, put on more than 75 pounds (34 kilograms) when she was pregnant with her daughter and has been struggling to return to her ideal weight - 145 pounds (65.7 kilograms). But she admits she's enjoying her new chocolate diet. She says, "I haven't been doing anything so far, except TrimSpa of course. We're coming out with a chocolate product which I'm sampling now... You eat two of the chocolates instead of taking the pills and it actually is yummy."
