Stern has been recording from his opulent dwellings because he spent much of his $500 million contract on building a property empire.

Stern can’t stand SiriusXM colleague Alex Cooper, the host of the podcasting behemoth Call Her Daddy, because of how big her empire has gotten, according to the U.S. Sun. The animosity runs so deep that SiriusXM works to keep them apart whenever the Los Angeles-based Cooper visits SiriusXM’s New York offices, according to the paper.

Signs point to SiriusXM not renewing its contract with radio legend Howard Stern—and his employees are preparing for the change. According to Howard Stern’s employees, “the writing has been on the wall for well over a year” that SiriusXM wouldn’t be renewing the radio host’s $500 million contract.
