The undercover reporter known as the "Fake Sheikh" has told the trial of Tulisa Contostavlos it was '"outrageous" to suggest he spiked the former X-Factor judge's drink.
Giving evidence at London's Southwark Crown Court, Mazher Mahmood, denied "manipulating" the 26-year-old after he told her she was being considered for a leading role in a Slumdog Millionaire-type film, possibly co-starring Leonardo Di Caprio.
The court previously heard that Contostavlos spoke about being able to get "white sweets" - allegedly code for cocaine - while at the Metropolitan Hotel with Mr Mahmood on May 10 last year.
The prosecution suggested that Mr Mahmood and his colleague "Nish" spiked Contostavlos's drink to "manipulate" her when they met at the hotel.
Mr Mahmood replied: "Absolutely outrageous."
Under further cross-examination, Mr Mahmood told a court he wanted to "expose criminality" and denied the reason for the expose was to create a "sensational story".
Tulisa, of Friern Barnet, north London, denies being concerned in the supply of class A drugs between May 10 and May 23 last year.
The jury was sent home and told to return to court on Monday.
