One Guy Links Madonna, A-Rod, Lenny

July 4, 2008 — -- There's one man in Hollywood who probably needs this long weekend more than anyone else: Guy Oseary.

Never heard of him? Surely you know his clients — Madonna, Alex Rodriguez, Lenny Kravitz.

He serves as manager for all three and not many others. And, as you probably know if you've been reading the headlines, he's had one hell of a week.

First, there were the rumors of Madonna's late-night trysts with the New York Yankees slugger. On Tuesday, Us Weekly magazine reported the two started hooking up after Rodriguez attended her April 30 concert in New York. The rumors persisted despite staunch denials of an affair from Madonna's publicist, Liz Rosenberg.

"[Madonna's marriage] is not on the rocks, and there are no plans for getting divorced," she told ABCNEWS.com. Rosenberg also brushed off rumors of The Material Girl and A-Rod being anything more than friends to People magazine.

"Madonna and Alex have the same manager, Guy Oseary," she said. "They have met. They know each other, and Madonna took her kids to a Yankees game last week. There's really not anything to comment on beyond that."

Oh, how that changed. Friday, The New York Daily News reported Rodriguez's wife, Cynthia, walked out on him as a result of the Madonna rumors. To whom did she run? Lenny Kravitz, aka, Oseary's second-biggest client, aka, Madonna's rumored ex-lover.

Madonna, 49, and Kravitz, 44, collaborated on her 1990 hit "Justify My Love." They were romantically linked at the time.

"Cynthia is a friend. ... She came [to Paris] to escape from everything happening in New York City," Kravitz said in a statement to reporters. He's in the middle of his Love Revolution Tour in Europe. "I opened my home to her as a friend, and I find it extremely hurtful that I am now being referred to as an adulterer."

Oseary didn't respond to ABCNEWS.com's request for comment.

"All roads are leading to him, and quite justifiably," said Ian Drew, editor at large and head of music coverage for Us Weekly magazine. "He tends to be a connector. He brings a lot of disparate people together. Everyone's saying that he facilitated this."

Added Marc Bass, who headed up his own Hollywood talent agency for decades before selling it this year, "It's an awfully awkward spot to be in. My guess is he's probably corralled all three of them separately to figure out what's going on. Most of the time the clients do come clean. They'll tell the manager exactly what's happening. But then the question is, do you discuss that with the public? You don't want to put out something that's potentially damaging."

It's new turf for Oseary, 38, who took on Rodriguez, 34, as his first athletic client in December 2007. He got into the entertainment industry young, as a teenage intern for Madonna's then manager, Freddy DeMann. He quickly won over The Material Girl with his passion for the music business and soon landed a gig as the head of Maverick Records, which began as Madonna's boutique label and grew into one of Warner Music's most successful wings. In 2005, Oseary pushed DeMann out of the way and scored the coveted title of Madonna's manager, heading up her 2006 Confessions Tour and negotiating her $100 million deal with Live Nation last year.

Besides Madonna, Oseary keeps a small stable of entertainment clients, including Kravtiz, David Blaine and the show "Last Call With Carson Daly." In addition, he's a partner in Untitled Entertainment, whose clients include Ashton Kutcher, Hilary Swank, Penelope Cruz and Naomi Watts. Oseary also has a handful of film and TV credits to his name, including producer titles for "Agent Cody Banks" and "Material Girls" and on-screen roles in "You Don't Mess With the Zohan" and the "Charlie's Angels" movies.

When he added A-Rod to his roster, Oseary fueled speculation that the Yankees hitter may transition out of baseball and into the entertainment biz.

"He's focusing on baseball and needs someone whose interests are aligned," Oseary told Daily Variety in December. "This is to help him have more control of his image and brand. ... Obviously, there are a tremendous amount of opportunities for Alex."
