Jennifer Lopez's marriage to Marc Anthony at a breaking point?

Us Weekly, reports on 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.

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?'"
