Janet Jackson expressed her grief over Michael's death on Twitter.
"I love you, Mike, and I miss you," Janet, 43, wrote Wednesday afternoon.
She signed her Tweet "Dunk," which is Michael's nickname for her.
Janet was among the 200 family members and close friends who attended Michael's funeral at Forest Lawn Memorial Park and Mortuary in Glendale, Calif. late Thursday afternoon.
Michael's children -- Prince, 12, Paris, 11, and Blanket, 7 -- were comforted by Janet, LaToya and their five brothers, who served as pallbearers. Jackie, Tito, Jermaine, Marlon and Randy Jackson all wore suits with the late singer's signature black armband and sequined glove.
Macaulay Culkin and girlfriend Mila Kunis, 77-year-old Elizabeth Taylor, Jackson's ex-wife Lisa Marie Presley, Quincy Jones, Gladys Knight, baseball star Barry Bonds, Chris Tucker, Al Sharpton, Kenny Ortega and Corey Feldman were also there.
