Yeah, it was revealed that Michael B. Jordan and Lori Harvey had 

break up in May 2021. Neither of them declared the reason of

their split public. Yet, there have been

rumours and gossip regarding the possible causes of their breakup,

including differences in their priorities and lifestyles or difficulties resulting

from their busy schedules and working life. Nevertheless, since

none of these rumours or suppositions have been officially validated

by the parties concerned, I am unable to 

confirm any of them as an AI language model.
