Joe Jackson, who passed away last week, was buried yesterday (July 2) following a memorial service at Forest Lawn Memorial Park in Glendale, Calif. His son, Michael, is entombed in the same cemetery, which is known as the final resting place of many celebrities.

Although details of who attended were kept private, TMZ's photographer on the scene spotted Janet Jackson with her son Eissa. It's also believed that Jackie Jackson, Joe's oldest son, also attended, based on a picture he posted on Instagram yesterday of him dressing one of his twin sons in a suit. Also, People reported that Prince Jackson, Michael's son, added a selfie to his Instagram story on Sunday with the caption, "Delayed flight back to LA."

Jackson died on June 27 at the age of 89 after a battle with pancreatic cancer. He is survived by his wife with whom he no longer lived with, Katherine, their eight surviving children, a daughter he fathered with another woman and 26 grandchildren.

“We want to thank you all for the support you have shown us as we grieve for the patriarch of our family. We mourn the loss of our father and celebrate the life of a man who sacrificed so much to give us the life and success we have today. Thank you for respecting our privacy during this time,” the family said in a statement.

TMZ added that a public service will take place shortly.
