UMG Says They Should Be Removed From Sara Rivers Lawsuit Against Diddy

Universal Music Group says they are catching legal strays when it comes to an explosive lawsuit against Diddy … and they want a judge to cut them some slack.

Here’s the deal … former “Making The Band” singer Sara Rivers is suing Diddy for alleged hostile and inhumane treatment … and her lawsuit named UMG as one of several dozen defendants.

The music corporation just filed a motion to dismiss the lawsuit against them … arguing they have no business being sued by Sara.

In new legal docs, obtained by TMZ, UMG argues the case against them should be dismissed because it’s time-barred … UMG says the federal claims are preempted by New York state law and that it’s an improper group pleading that fails to state a claim.

UMG also says the parts of Sara’s lawsuit that involve them are irrelevant to her claims against Diddy … and they say that out of over 1,003 paragraphs in the original lawsuit, only 10 pertain to UMG.
