Talk about a smart cookie. Even though Vicki Gunvalson and Brooks Ayers were never married, it looks like the former couple had a set of "guidelines" for their relationship. There's a new report that says Gunvalson and Ayers supposedly signed a "renter's agreement" while they were together.

Even though the couple announced their split last week, they were on-again and off-again for several years. Now, according to OK! Magazine on Wednesday, Gunvalson supposedly made Ayers sign a contract before he moved in with her.

A source close to the reality television star said, "Vicki and Brooks have a renter's agreement that was simply an agreement that said any rent paid by Brooks did not count as equity on Vicki's house."

The insider added, "It was only a contract that they had with each other and Vicki continues to own the house completely. It was just a simple renter's agreement... nothing more, nothing less."

Earlier this week the couple made a joint statement about their break-up on her Facebook page.

Gunvalson wrote, "After much prayer, thought, counseling, and consideration, we have decided to end our four year relationship. We both wish nothing but a great future for each other. We have come to realize that one can indeed love someone in their heart, but that the time may come for their lives to take separate paths."

The blonde beauty added, "There will be no further statements or interviews regarding our relationship as we choose to move on with our lives. we choose to live our lives in the public eye, we thank you for your understanding and ask privacy during this difficult time."
