Mariah apologizes for MJ tribute performance

Mariah Carey apologized for her performance at Tuesday's Michael Jackson memorial, saying she "wasn't able to pull it together and really do it right," and that she was "sorry."

Carey said she was too emotional to perform Jackson's hit "I'll Be There" the way she would have liked.

She made the comments via her Twitter page:

"Trying to sing today was basically impossible for me. I could barely keep myself from crying. I'm sorry that I wasn't able to pull it together and really do it right, but I was literally choked up when I saw him there in front of me. One thing I know is, we will never really have to say goodbye to MJ. His legacy lives on through his music and the millions of people he inspired with his timeless music. He will be forever in our hearts."

• The Encino Neighborhood Council will hold a meeting Wednesday to address "concerns over continuing impacts from sightseers and media in the weeks and months ahead," according to a press release from the council.

Since Jackson died, a portion Hayvenhurst Avenue has been blocked off to traffic as fans created a Jackson memorial and media waited for a glimpse of the family.

• Jackson's dermatologist, Dr. Albert Klein, offered a lukewarm denial of rumors that he's the father of Jackson's children.

"All I can tell you is, to the best of my knowledge, I am not the father of these children," Klein told "I can't answer it any other way. I don't want to feed any of this insanity going around.

"These are brilliant children and I want them in no way to be harmed ... People should know the depth of [Jackson's] love of his children."

• The producer of the memorial said the event's most climactic moment, when 11-year-old Paris Jackson offered a loving tribute to her father, was not scripted.

Paris, speaking through tears, said, "Ever since I was born, daddy has been the best father you could ever imagine," she said. "And I just want to say that I love him so much."

Ken Erlich, the producer of the memorial, told Entertainment Weekly that the moment was in no way planned. "A lot of the show was not scripted," he says. "A lot of the speakers spoke from their heart. ... When [Paris spoke], I had asked the family to come up if they wanted to and say something. I thought, frankly, that we were going to get the brothers and the sisters. This went way beyond that, obviously."
