Ms. Chen hasn't been on "The Talk" since Mr. Moonves resigned under pressure from CBS's board and controlling shareholder National Amusements Inc. The CBS show's founding co-host will announce her departure on Tuesday's show via a videotaped message, CNN reports.
Chen, 48, did not directly address any of the controversy surrounding her husband or his departure from CBS as chairman and CEO. They said their source said she may have been asked to do so, and should be making the official announcement herself soon.
Chen is expected to remain on "Big Brother", at least until the show's season finale on September 26.
In the statement, which she tweeted out, she said, "Leslie is a good man and a loving father, devoted husband and inspiring corporate leader". He has always been a kind, decent and moral human being.
Panelists on competing daytime talker The View also have addressed Chen's absence as well as her return to Big Brother four days after her husband's CEO ouster.
It's unclear how long Chen could remain on board at "Big Brother", although a source told the Journal that she hoped to stay with the program for "years to come". In the past, she had not used his last name.
Back in July, Chen came out and immediately supported her husband when the first allegations about sexual misconduct arose. She's hosted the show since 2000. I fully support my husband, and I stand behind him and his statement'.
