Lisa Marie Presley claims she's disappointed at the "empty space" surrounding Michael Jackson's tomb -- so she's now challenging MJ 팬 to flood the place with sunflowers ASAP.



LMP just 게시됨 a message on her MySpace page describing her recent visit to Michael's grave site at Forest Lawn. Presley -- who was married to MJ back in the '90s -- says she believes Michael "deserves more" than the "few bouquets, candles and gifts" that currently surround Michael's grave.

Presley -- who notes Michael's infatuation with sunflowers -- is calling for 팬 to send a "Sun Shower" to the tomb because, "I know how much he loved and appreciated being showered with Gifts and 꽃 의해 his fans."

Presley suggests that if every 팬 sends "one silk sunflower" to the site, "the whole area around him and in front of him ... could be filled up in no time."
