The 61-year-old star believes her beloved sibling - who died of acute Propofol intoxication in June 2009 aged 50 - is around and makes his spirit known by causing lights to ''flicker''.
She told E! News: ''That's him. I know it's not the bulb. They're flickering. So when that happens that means that he's around.''
The 'Just Wanna Dance' singer recently sat down with medium Tyler Henry and was astonished by how well Michael ''came through'' to answer her questions during the session.
Speaking about their meeting - which will air on the finale of 'Hollywood Medium with Tyler Henry' later this week - La Toya said: ''Not just me but everyone in the family, there are a lot of unanswered questions of course. Tyler answered them for me. He came through really well which was great.
''I had questions in my head, but before I could even ask Tyler the questions he was giving me answers to them and he didn't even realise he was doing that. It was just everything I wanted to know. Tyler was there to deliver it to me.''
Tyler previously revealed Michael ''came through'' to explain the final moments before his death, which ultimately saw his personal physician Conrad Murray convicted of involuntary manslaughter after administering the lethal dose of painkillers.
And after claiming to have made contact with Michael's spirit, Tyler promised the upcoming episode of his show will give his fans a ''deeper sense of closure'' about the 'Beat It' singer's death.
He said: ''It's hard to even talk about the subject casually because he did, he came through! It's still one of the most surprising, bizarre, surreal experiences in my life...
''He conveyed various messages and I think La Toya was still very curious about the nature of what exactly happened to Michael in his final moments. There were some questions about the timeline as far as who was around at the time.
''And so Michael basically came through, to the best of my ability I conveyed the timeline of what I saw to be true as far as painting that picture.
''It just helped I think provide some validation for them because there were some questions about were certain people in the room at the time or if they're weren't. Things like that I think can really help people put things to rest.
''But especially when it's such a public figure, I think everyone who watches this episode will find a deeper sense of closure around Michael's passing as well.''
