When they do go out together he ignores her but does not let her talk to anyone

This singer was bordering on A list at one point in her career.

Then she started dating this at the time married A list mogul.

Her career went nowhere and while he goes out almost every night, he makes her stay home because he is too insecure for her to go out without him.

When they do go out together he ignores her but does not let her talk to anyone except pre-approved females.
