did stefon diggs strangle cardi b

No, there is no credible evidence that Stefon Diggs strangled Cardi B, and such an event has not been reported by reliable news outlets.
What actually happened
Recent reporting states that Stefon Diggs has been charged with felony strangulation and assault in Massachusetts after an alleged altercation with his private chef, not with Cardi B. The police report and news coverage describe an argument over back pay that allegedly escalated into him striking and choking the chef, leading to the current criminal case.
Stefon Diggs and Cardi B
Multiple outlets note that Cardi B is Diggs’ partner and that the two recently welcomed a baby together, but she is not the alleged victim named in the criminal complaint. While there is intense online discussion and gossip around their relationship and his legal troubles, no reputable source reports him strangling Cardi B.
Why the rumor is misleading
The mix of a serious criminal charge (strangulation of the chef) and Cardi B’s public profile has led to confusion and exaggerated forum gossip. Sharing or repeating claims that he strangled Cardi B misrepresents the known facts and unfairly spreads a false, more sensational version of events.
