Pilar Sanders wants everyone to know she did NOT cheat on Deion and now she wants to take a lie detector test to prove it.

Sanders is still fuming about the allegations Deion's daughter Deiondra made about her during an epic Twitter rant last month in which she claimed Pilar was a "gold digging h*e" who cheated on the NFL legend.

Now, Pilar's attorney, Larry Friedman, says, "It is extremely unfortunate that, in addition to the mental distress caused by the unexpected and untimely filing of the divorce by Deion Sanders, he has not stopped his daughter Deiondra from falsely accusing my client, Pilar Sanders, of infidelity in order to cause her more pain and suffering and further damage her character and reputation."

Friedman adds, "This matter doesn't require praying for Pilar as Deion has stated; it calls for telling the 'truth' — as well as a retraction of the false accusations made about Pilar and a public apology."

"Perhaps it's time for the parties to submit to and release the results of a polygraph examination to determine whether infidelity was committed during the marriage and to put an end to the speculation once and for all."

Deion apologized for his daughter on a radio show last week — apparently, it wasn't good enough.
