Britney Spears and husband Sam Asghari have split after a "nuclear argument" that centred around allegations of cheating, according to TMZ.
The website reported Asghari had confronted the 'Toxic' singer a week ago over rumours she had cheated on him.
The pair have been married for 14 months.
TMZ claimed Asghari had subsequently moved out of their home and is now living alone.
They also reported a source as saying: "It's only a matter of time before Sam files for divorce."
The outlet also said it had no verification whether the cheating rumours were true.
The pop star and actor met in 2016 and married in June 2022.
US magazine People reported in March that rumours were circulating about the couple having marital struggles. Asghari's rep shut the rumours down after he was seen not wearing his wedding band.
