Jennifer Lopez and Marc Anthony's Marriage at "Breaking Point"

The new issue of Us Weekly, on newsstands tomorrow, reveals the behind-the-scenes crisis going on in Jennifer Lopez's third marriage to Marc Anthony.

Rumors swirled that Lopez's marriage was on the rocks after she showed up to the premiere of The Curious Case of Benjamin Button last week without her 8-carat diamond engagement ring, wedding band - or ever present husband, Marc Anthony (who was spotted in Las Vegas sans wedding band the weekend before).

Multiple sources confirm to to Us Weekly their marriage is at a breaking point.

"They both didn't wear their rings on purpose," a mutual pal of the married couple of four years (who renewed their vows in October) tells Us. "Nothing Jennifer does is without purpose."

While Anthony's rep insists to Us, "They are doing great," a source tells Us deep trouble has been brewing.

"He's very, very controlling of her," a close Anthony pal tells Us. "The skirts aren't as short. You don't see so much of that booty anymore." The new Us Weekly also reports that Anthony also picks out Lopez’s clothes and keeps tabs on her phone calls.

But Lopez -- who once claimed she "loved getting his opinions" -- has become less interested in his approval since the birth of their 10-month-old twins, Max and Emme.

"She walks in from work, washes her hands and grabs the babies," a longtime friend tells Us. "With him, it's almost like, 'Ugh, they're crying again?'"

Another problem: Lopez -- who once commanded $15 million per film -- "blames Marc for her career going down the tubes," says a mutual pal, adding that she's bitter about the failure of their 2006 drama, El Cantante, which only grossed $7.5 million. (Her 2002 flick Maid in Manhattan earned over $94 million.)

"Jennifer looked around and said, 'This is my life now? I'm a Long Island housewife?'" a pal says. "She hates that everything she worked for went down the tubes."

Look back at Lopez's style over the years.

Lopez isn't the only one with growing resentment toward her husband. Her best friend, Leah Remini, also can't stand him.

"It if was up to her, Leah would just break them up today," a pal says.

Anthony has also been badmouthing his wife. One night after their tense family Thanksgiving in which the couple "didn't sit together," Anthony hit NYC hotspots Bungalow 8 and Marquee, where he was spotted with his hand on a woman's thigh and overheard complaining about his wife to a group of women, "telling them, 'She's making me miserable,'" a source says.

His club spree didn't stop there: The next night, he was photographed by TMZ.com partying sans wedding band with pal Eva Longoria Parker and Russell Crowe in Las Vegas. (A source says, "According to Jennifer, he didn't cheat.")

The pair, who hadn’t been spotted together since Oct. 23 -- and the very public removal of their wedding bands -- had dinner Tuesday at Beverly Hills restaurant Luau, which they left holding hands.

(Lopez is no stranger to shows of strength, though: after she and Ben Affleck called off their first wedding, they had dinner at the paparazzi-laden Ivy restaurant in L.A.)

Just going by seeing her on TV and reading interviews - I don't think she'll ever be happy. I think she has too-high expectations of love and marriage.

I am sad for them if this is true.

When the photo of the premiere was posted, that's the 1st thing I commented on. Where was her ring?

It's sad! They have 2 kids. They seemed happy. Kids can stress a marriage though. It's hard!

I can see this, the movie el cantante i think it mirrors their life a lot because there have always been rumors that he is a cokehead just like Hector Lavoe who was the singer he portrayed.

I hope they can work through their differences though, because i think they do love each other.

I feel bad because they just had babies. I hope they make it, if for nothing else but that there has to be at least one hollywood marriage that can last!

I don't understand this - if you don't want speculation about marital trouble then why would you leave your ring off when you go out in public? I never get it when stars take their rings off before they are ready to admit troubles - you KNOW the tabloids will jump all over it and make you miserable. Just suck it up and wear the stupid ring to keep people off your back!

Wow, a relationship that started with cheating isn't working out. Shocking!

Same thing happened to my dad and his 2nd wife. They both cheated on their first spouses (she was pregnant by her first husband at the time to make it even worse) and then after they were married for about 15 years the wh0re cheated on my dad and divorced him.
