London, Aug 19 : The executors of Anna Nicole Smith''s estate are planning to take legal action after it emerged that an escort service in Las Vegas has been distributing flyers branded with the late star''s nude image.

The legal team in charge of Smith''s affairs got angry after they came to know that a Nevada-based company has been allegedly using a topless picture of the late star 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 dollars special".

"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,” The Daily Star quoted Ron Rale, the lawyer for Smith''s estate, as telling TMZ. com.

And the star''s former boyfriend Larry Birkhead, who is also the father of her daughter Dannielynn, said: "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."

Smith died of an accidental overdose in 2007. (ANI)
