Janet Jackson has been dumped from this Sunday's Grammy Awards ceremony.

People magazine says the network, anxious to ward off criticism of the Super Bowl controversy, canceled its invitation to Jackson to appear on the show.

Michael Jackson's younger sister was to have introduced a tribute to Luther Vandross.

MTV, which produced the half-time show during the Super Bowl, is livid with Jackson. Both CBS and MTV are owned by the Viacom Corporation. 

'Janet Jackson engineered it,' MTV CEO Tom Freston said on Wednesday.

Jackson apologized a second time yesterday via videotape. 'I am really sorry if I offended anyone. That was truly not my intention. My decision to change the Super Bowl performance was actually made after the final rehearsal. MTV (who produced the half-time show at the Super Bowl), CBS (who telecast the Super Bowl), the NFL (National Football League, which hosts the most watched sporting event in America) had no knowledge of this whatsoever, and unfortunately, the whole thing went wrong in the end,' she said.

Her accomplice at the Super Bowl, pop star Justin Timberlake, is scheduled to perform at the Grammies. He has also been nominated for five Grammies, including Album of the Year.

It is unlikely that CBS will cancel its invitation to Timberlake.
