Dr. Dre's estranged wife Nicole Young officially challenged his prenuptial agreement after she filed for divorce from the mega producer after 24 years.

Dre surprised Nicole and her attorney by answering her divorce petition and revealing he had an ironclad prenup all this years.

In new legal documents obtained by TMZ, Nicole claims the prenup is "null and void" because Dre ripped up the documents two years after they were married.

In the court papers, Nicole, 50, said she was "reluctant" to sign the prenup and felt pressured and intimidated by Dre.

"I was extremely reluctant, resistant and afraid to sign the agreement and felt backed into a corner. Given the extraordinary pressure and intimidation by Andre, I was left with no option but to hire a lawyer (of course, with the help of Andre's team of professionals) and unwillingly signed the agreement very shortly before our marriage."

She continued, "Andre acknowledged to me that he felt ashamed he had pressured me into signing a premarital agreement and he tore up multiple copies of the agreement in front of me. Since the day he tore up the agreements, we both understood that there was no premarital agreement and that it was null and void."

Nicole (pictured with Dre and their daughter, Truly Young) didn't keep the shredded documents as evidence to present in court.

Fans say Dre probably brought up the subject of a prenup 2 years after their marriage because his wife nagged him about it, and he told her he destroyed it to shut her up.

Men everywhere praised Dre for having a prenup to preserve his assets. The 55-year-old father-of-five has a net worth of $800 million. Nicole would have been entitled to half of his wealth if she'd thought to keep the shredded documents as evidence to present to a judge.
