Mariah Carey & Nick Cannon divorce RUMORS: Hip-Hop power couple going through 'marriage struggles,' leading separate lives with twin girls?

Apparently, Mariah Carey is a little too "diva" for husband Nick Cannon. Or is it the other way around?

A recent report in the National Enquirer claims, “What began as behind-the-scenes bickering has turned public as a bitter Mariah launches media attacks on the father of her 2-year-old twins, son Moroccan and daughter Monroe."

Apparently, the former "Amercian Idol" songstress "has had enough" with the "Wild n' Out" star.

And why, exactly?

An alleged insider reveals, "[Cannon] may be jealous over the handsome singers Mariah has been working with."

Well that explains everything.

The infamous gossip tabloid claims that Carey keeps poking fun at her hubby during TV and radio interviews, which clearly shows that the couple's going through a "rough patch."

Okay, then.

Carey and Cannon are supposedly "leading separate lives" - which explains why they didn't celebrate Valentine's Day together.

But wait a second... what's up with these sexy photos Carey posted while "waiting for her Valentine" on Instagram last week?

Yeah... it looks like the couple's relationship is doing just fine:

A "legit" rep informs Gossip Cop that there's "no truth whatsoever" about such "marriage struggles." Surprised?
