Take heed if you are planning on flying RHOA cast member NeNe Leakes and her hubby, Greg, to your city and paying all their expenses to host your charity event: she does not honor her commitments.

This story will be in the NY Post’s Page Six tomorrow, but we’re giving you the scoop on Sandrarose.com first!

NeNe and her husband Greg were invited to Boca Raton, Florida by “Women On the Move” founder Leslie Harris (pictured, left) to host an event to raise funds for breast cancer research.

Harris founded “Women on the Move” to raise breast cancer awareness after her own grandmother succumbed to the disease. She planned to add a little star power by tapping Real Housewives of Atlanta diva Lisa Wu-Hartwell and Leakes to host the inaugural “Unveil Your Pink” charity auction to benefit Susan G. Komen For The Cure this weekend.

Harris, who is a millionaire entrepreneur, paid all of the Leakes’ expenses and put the couple up in a $2,000 a night room at the 4-star Brazilian Court Resort hotel. It was all good until Leakes called Harris today to inform her that she was not doing any press.

After a polite inquiry by Harris who reminded NeNe of her contractual obligations to do press, NeNe said, “Well, I’m entitled to change my mind if I want to.”

When Harris told NeNe she could go home if she wasn’t going to do press, NeNe allegedly responded, “Buh bye, BITCH!”

I’m told that Harris immediately called the airport and promptly canceled NeNe’s return flight to Atlanta, leaving her and hubby Greg stranded at the airport!

Harris then faxed over a copy of the signed contract to her attorney. A lawsuit will be filed on Monday against NeNe Leakes for breach of contract.

According to my spies, NeNe had no intentions of hosting the event or doing any press as contractually agreed.

She simply wanted a free trip to Florida so she and Greg could attend a star-studded event taking place in Miami this weekend on South Beach with such celebs as Boris Kodjoe, his wife Ari, Steve Harvey and Nia Long.

My spies pointed to this tweet posted by NeNe earlier today as proof that NeNe had no intentions of honoring her agreement with Leslie Harris in Boca Raton.
