The 28-year-old heiress — who is being sued for $8 million for failing to promote her 2006 comedy “Pledge This!” — was asked by lawyers during a pre-trial hearing in Miami Thursday if she keeps a diary for business meetings.

“I just press my name and Google it and see,” she told the court.

Asked by lawyers about her calls from the producers, she testified: “With my phone I never know, because I lose it all the time. I probably get a new cellphone, like, every two weeks.”

When shown a copy of her cell phone bill, she replied: “I’ve never seen a phone bill of mine in my life.”
