Prince, Paris and Blanket were spotted in Gary on Tuesday visiting their father's boyhood home, TMZ reported.

The children's co-guardian, Michael Jackson's mother Katherine Jackson, along with their aunt, La Toya Jackson, were also seen in Gary.

The pop star will be honored at the "Goin Back to Indiana" celebration, which kicks off Wednesday night with a candlelight vigil in front of his childhood home.

Jackson's kids are also expected to throw out the first pitch at a Gary SouthShore RailCats baseball game this week.

Jackson died on June 25, 2009. He was 50.
