A fourth marriage is not on the horizon for Jennifer Lopez.

There was talk that Lopez is planning a wedding with her boyfriend, dancer Casper Smart, after the following tweet was reportedly posted Monday on fashion designer Roberto Cavalli's Twitter feed: "Today , Jenifer Lopez. Call me…… She ask me. To create a special dress. For her next weding. !"

However, Cavalli's rep told  People magazine that the account was hacked and that there's no truth to the tweet. J-Lo's rep also denied the marriage rumors.

Lopez, 42, and Smart, 24, have been linked since last fall. She's been married three times, most recently to Marc Anthony, from whom she split last summer.

Meanwhile, Lopez' longtime manager and business partner Benny Medina had some choice things to say about her choice of men. According to RadarOnline, Medina told the April edition of Vogue that Lopez can't have "a real meaningful relationship," because she picks the wrong kinds of men. "The thing that I always sort of wished is that she would give herself time to just naturally meet someone, instead of having obsessive guys pursue her," he said of her "serial monogamy."

Medina continued, "The ease with which that obsession becomes a relationship I think sometimes works against her ability to have a real meaningful relationship. And she never half does anything. When she commits to anything in her work, her life, or her relationships, she is in it."

As for her new man, Medina said of Lopez, "She's not oblivious to her own reality right now, as in, 'Damn, I'm 42 with a 24-year-old. Why?' We talked about it yesterday. She was just like, 'It's not even the age, Benny. It's actually that I just came out of a relationship where I felt like I was kind of not getting what I needed.  And I'm open! So somebody who steps in right now and is actually touching me in a way - it's very fertile ground!'"
