Kelly Clarkson claims her ex-husband/former manager told her she wasn't hot enough to appear as a judge on "The Voice" ... even though she eventually got the gig.
The 'Idol' alum reportedly made the allegation about Brandon Blackstock -- who she divorced in 2022 -- to a California labor commissioner in '23 while trying to determine how BB had handled her finances during their relationship, per a court doc obtained by the Post.
According to the outlet, Clarkson gave testimony in which she alleged Blackstock had told her she wouldn't pass as a 'Voice' coach 'cause she didn't have the sex appeal for it.
She reportedly said Blackstock told her NBC was "looking for a more sex symbol type" ... and then allegedly invoked Rihanna's name as a comparison to point out who Kelly did not look like, and which he cited as a reason for not pursuing the coaching gig she wanted.
Kelly had apparently relayed to Blackstock she wanted to join the panel of judges for a while -- but went on to claim Blackstock rebuffed her, arguing back that not only was she not good looking enough for 'TV,' but claiming the network was interested in signing a Black star.
Blackstock reportedly said Kelly and then-judge Blake Shelton were just "too similar." Of course, Kelly did eventually join "The Voice" in 2018 ... and stayed on for several seasons. Blackstock testified that he got Kelly the job in 2017 after going to an NBC exec and threatening that she'd go back to 'Idol' if they didn't sign her ... and when asked what it would take to snag her at NBC, he reportedly said it was going to cost "Blake money."
The allegation comes amid a recent finding by the same CA labor commissioner that Blackstock had overcharged Kelly during their professional relationship -- which coincided with their marriage. TMZ broke the story ... he now owes her $2.6 mil for fees he collected.
That cash also touched on this 'Voice' drama ... where the labor commission found he'd overcharged her about $1.98 million in booking the gig. Blackstock has vowed to appeal.
