Ashton Kutcher's Alleged Mistress Brittney Jones -- I Feel Lied To

Only in Hollywood can someone who slept with a married man claim they feel "lied to" -- but that's what Brittney Jones, Ashton Kutcher's alleged mistress, told our photog yesterday.

As TMZ first reported, Jones -- whose alleged tryst with Kutcher in 2010 was heavily denied by his camp -- says she felt vindicated when Demi Moore finally pulled the plug on her marriage to Ashton.

Jones said she hasn't spoken to Ashton lately but she wishes him and Demi the best.
