Why would a parent meet their estranged child well after they were famous?
Are you talking about any one famous person in particular? If so, who?
If you are NOT talking about any one particular famous person but asking this question as a general hypothetical, then there could be any number of reasons, depending on the particulars of the specific case. For example, in some conceivable cases, the parent might have wanted for many years to get back in contact with the child, but didn't have any idea how until the child suddenly got famous.
It's not uncommon in EMO music for singers & musicians to write songs about their estrangement & I think it's theoretically possible that the parent might hear the song & feel bad.
