Michael Jackson and Stevie Wonder back in the day

*During the Memorial Day weekend, Stevie Wonder and three of his children paid a visit to Michael Jackson’s tomb in Glendale, Calif.

According to TMZ.com, Wonder was at the Forest Lawn Cemetery to pay respects to his mother Lula Mae Hardaway, who had died in Los Angeles exactly four years earlier (May 31, 2006) at age 76.

After visiting his mother, Stevie’s kids insisted they view Jackson’s crypt as well.

Wonder and MJ, both Motown alumni, shared a close friendship. Wonder performed at the King of Pop’s memorial last year and told the crowd he often let Michael know how much he loved him … and was “at peace with that.”
