Mariah Carey is seriously affected by her divorce to Nick Cannon as she continues to struggle during her world tour.

The singer, who hit some shockingly bad notes last week at the opening of her tour – The Elusive Chanteuse – it was evident that there was something wrong with Mariah. And this time it wasn’t on her behalf.

Or was it?

Nobody really knows whether Mariah cheated on Nick during their marriage, but I’m going to give her the benefit of doubt because she’s a “classy diva, darling” and doesn’t seem like one of those stars to step out of her marriage, knowing she has two children at home.

Nick, on the other hand, is a player.

Having constantly boasted on sleeping with Kim Kardashian, Nicole Scherzinger and Christina Milian, the ‘America’s Got Talent’ doesn’t find shame in admitting he used to be a manwhore in his younger days.

The streets have been talking, and so has TMZ, who allege that there may be something going on between Nick and newly-divorced, Amber Rose.

Amber split from Wiz Khalifa who she accused of cheating during their marriage.

Well, that’s funny and ironic at the same time because sources are snitching, alleging that Amber was hooking up with Nick while Cannon was still with Mariah.

So this brings us back to Mariah Carey and how awful she’s been sounding during concerts. Hitting certain notes is out of her range — not because she can’t do it, but because she’s dealing with the stress of being a single mother of two while being reminded that her cheating husband is still hooking up with the woman he cheated on her with.

We’ll say “alleged” because Nick hasn’t come forward yet to admit he cheated on Amber, though it’s becoming evidently clear that he’s been smushing Amber’s tush in.

Cute phrasing right?

Globe magazine adds: “Mariah Carey is all washed up! That’s what fans are saying after the diva forgot lyrics, struggled to hit her famous high notes, and couldn’t seem to carry a tune during a recent concert kicking off her world tour.”

The insider continued: “While performing ‘We Belong Together,”’she grappled with a broken mic stand and a weak voice until she said ‘Wait a minute I can’t go on.’”

Let’s hope this doesn’t end up putting Mariah in one of her depressions again.

Hardcore Mariah fans, you know what I’m referring to.
