It is your exclusive first look at the new Anna Nicole Smith, who is slimmer and sexier than ever before. And only "Extra" has a behind-the-scenes look at Anna posing for a commercial for Trim Spa, the diet supplement that she claims helped her get back into model shape.

Trim Spa's founder and CEO, Alex Goen, says that Smith has lost at least 30 pounds using his product. Goen says, "Look for yourself, it is absolutely extraordinary. She is at the weight now when she used to be a Guess Jeans model."

The reality of Smith's weight struggle has been well documented; she's gone from A-list Playboy playmate to an E! True Hollywood Story. But no one could have scripted the latest bombshell from her previous look. Smith says, "I was in a depressed state, and all I did was eat."

So how does it work? The company claims the supplement contains a fat blocker, but not ephedra, which studies claim can cause an irregular heart beat. Goen says, "She simply took a few tablets before each meal starting in April."

The company, and now "Extra," has learned that the commercial is just the beginning for Smith. Look for a major modeling endorsement sometime soon.
