Michael Jackson's ex-wife is begging his fans to lay flowers at his grave.

Lisa Marie Presley - who was married to the late 'Thriller' singer from 1994 to 1996 - was so shocked by the sparseness of his burial site in Forest Lawn Memorial Park, California, she has written an open letter to his supporters appealing for them to send sunflowers.

The brunette star - who has four children, Riley, 20, Ben, 17 and 19-month-old twins Harper and Finley - wrote: "Greetings MJ Fans..

"While visiting him a few days ago at Forest Lawn, Riley and I couldn't help but notice that, while there are a few bouquets, candles and gifts there is a very large empty space around him and in front of him that could use a whole lot more.

"I know how much he loved and appreciated being showered with Gifts and flowers by his fans, I thought if whoever wants to bought just one silk sunflower each and sent it, the whole area around him and in front of him (As well as the two large empty vases that sit on either side of him) could be filled up in no time, which would be much more appropriate than what the current status is right now."

Lisa Marie revealed she has already started off her campaign with a vase of silk sunflowers, which were special to the couple during their marriage.

She explained: "Some may or may not know this but his favourite flower was the sunflower. They made him happy because they looked happy to him, Thus, he called them The Happy Flower.

"When we were married , I would try and fill up rooms with them wherever he was.

I wanted to bring something to place near him that he liked and that wouldn't die so I brought a large vase of silk sunflowers and placed them near him. This barely made any kind of dent in the atmosphere so I thought of maybe letting those who care know what the situation is and how we can solve it.

"We can all cause a "Sun shower" if you will... He deserves to be flooded and surrounded , LETS SURROUND HIM! (sic)"

Michael died of acute Propofol intoxication last June aged 50.
