SMITH'S ESTATE PLANS LEGAL ACTION OVER ESCORT PICTURES

The legal team in charge of Smith's affairs are fuming after they discovered a Nevada-based company has been allegedly using a topless picture of the star - who died of an accidental overdose in 2007 - to advertise their services.

The flyer shows an image of what looks like the late model - renamed Mandy on the promo - to advertise their "$25 special".

Ron Rale, the lawyer for Smith's estate, tells TMZ.com, "Nobody is authorised to use Anna Nicole's image, name or likeness without the appropriate consent from her estate. We will immediately look into this."

While the star's former boyfriend Larry Birkhead, the father of her daughter Dannielynn, adds, "This is highly inappropriate. This is going to be the most expensive trick this company has ever tried to pull. It's definitely going to be worth more than $25 when it's all said and done. It's disrespectful."
