"Matt and I are not good with dates with our marriage," the 40-year-old Brazilian model revealed in an interview with Entertainment Tonight, published Tuesday. "We go back and forth all the time."

Alves and McConaughey, 52, were indeed married on June 9, 2012 during a three-day extravaganza in Austin, Texas.

When ET confirmed the date of their marriage, Alves jokingly said, "OK, I need to write it down. Somebody write it down. I need a reminder for this."

"I had my tequila already and I was just feeling very feisty and I was going back to Matt like, 'No, you got the date wrong.' And he goes, 'No, you got the date wrong,' " she told ET.

"We're going back and forth and my friend wanted a beer, so I'm looking for a beer and I had one of the koozies," the model continued. "I opened the drawer to grab a koozie and right there — I started cracking up so bad — it was a koozie from our wedding, and both Matthew and I were wrong."

Alves and McConaughey first met at a club 16 years ago, the model told ET. The couple now shares three children together: Levi, 13, Vida, 12, and Livingston, 9.
