OWN’s "Oprah’s Next Chapter" had a hefty 3.5 million viewers when the late Whitney Houston’s daughter, Bobbi Kristina, appeared for her first interview since her mother’s death, but it was a different story a week later, reports the New York Post.

Last Sunday’s episode — the week after Bobbi Kristina — featured Oprah Winfrey’s highly publicized interview with singer Lady Gaga. Despite heavy promotion, viewership was down a huge 77 percent to only 800,000. That means the show lost a stunning 2.7 million viewers week to week.
