Janet Jackson has no plans to ever see her late brother Michael's concert documentary movie This Is It - because it would be too painful for the grieving star to watch.

The film, which features video footage of the King of Pop rehearsing for his ill-fated London residency, has been a huge hit with fans and recently passed the $200 million mark at the global box office, just three weeks after its release.

Members of the Jackson family, including patriarch Joe, and Michael's brothers Jermaine, Tito, Jackie and Marlon, all turned out for the Los Angeles premiere of This Is It last month - but Janet refuses to watch it. And she admits even walking past the promotional posters for the film gets her choked up with emotion.

In an ABC News exclusive, Janet says, "I have not seen it. I definitely won't, not right now. I don't know if I'd ever see it. (It's) too soon, too hard. It's hard when I see the posters around the city, the commercials, the trailers (on TV). It has (caught me off guard emotionally)."

The Thriller superstar died in June, shortly before he was due to kick off his mammoth tour.
