America's favorite love affair between a former Fly Girl and a Puerto Rican skeleton may be coming to a tragic end. That is, if Leah Remini has anything to say about it!

According to Us, both Jennifer Lopez and Marc Anthony have been sighted lately without their wedding rings on, the Hollywood equivalent of wearing a novelty t-shirt that says, "DON'T ASK ME ABOUT MY FAILING MARRIAGE" in block type. So who's to blame, and who's ready to offer her friend a comforting e-meter to cry to?

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."

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.

Duly noted, "Leah Remini's pal"! We had wondered why Lopez hadn't worked in film since 2006, and now we know who to send flowers to was responsible. However, we question the logic behind fleeing one controlling home for a Scientology-approved safe house. J-Lo, you may think you want your acting career back, but is a recurring guest arc on My Name is Earl really the best comeback you can muster?
