Mazher Mahmood, a Pakistani-origin reporter for 'Sun on Sunday' tabloid, was alleged to have "misled" the court during the collapsed drugs trial of singer Tulisa Contostavlos at Southwark Crown Court in July last year.
He was charged alongside Alan Smith, who was his driver.
Crown Prosecution Service (CPS) spokesperson Nick Vamos said: "After carefully considering all of the evidence the CPS has decided that there is sufficient evidence for a realistic prospect of conviction and it is in the public interest to charge both men.
Former N-Dubz singer Tulisa had gone on trial charged with supplying a Class A drug, which she denied, after it was alleged she had brokered a cocaine deal.

It had featured in a 'Sun on Sunday' story in June 2013, following an investigation by Mahmood.
A judge threw out the case and following the collapse of the trial, Mahmood was suspended by his newspaper group.
"I deny the offence. I will vigorously contest it at court. In the meantime I have nothing further to say."
Mahmood has spent 25 years as an undercover reporter, in which time he claims to have helped put more than 100 criminals behind bars.
He and Smith will appear at Westminster Magistrates' Court in London on October 30.
