Retired NBA great, Reggie Miller, seems to be doing more with his retirement than sideline commentary. He's rumored to be on the prowl for women as of late ... married ones at that.

Miller must've pissed off the wrong husband recently, because a man spent a nice amount of cash over the weekend to embarrass the former Indiana Pacers guard, by having a banner flown back and forth along the Southern California coastline -- from Malibu to Redondo -- with the words "REGGIE MILLER STOP PURSUING MARRIED" plastered on it.

According to Jacky Jasper's DiaryofaHollywoodStreetKing.com (HSK), Miller has been pursing the fiance of Alex von Furstenberg, a Malibu resident and surf shop owner locally. He reportedly started up a conversation with her recently, and then waited for her to leave the local Country Mart before following her down Malibu's PCH highway begging to see her again.

Miller then began to constantly try to contact her, before von Furstenberg filed for a restraining order, after nearly three months of trying to woo his wife Ali. Sources told HSK that several other women have had similar experiences with the former NBA star.

While Miller has yet to comment on the allegations, reports say he and von Furstenberg have even had a confront Miller about the situation, where Reggie threatened him, saying "he had friends with guns."

"I was very upset about Reggie's behavior towards my fiancé," von Furstenberg said, according to HSK. "I think people in Malibu share my views that being a famous basketball player should not provide some sort of shield against inappropriate behavior. Reggie sincerely apologized to me on a phone call with Ronald Richards, his attorney, and myself. I cannot comment further on the matter as I believe it has been resolved."
