The 20-year-old actress has lashed out at the ''disrespectful'' people who had scribbled red graffiti all over the monument, which was presented to King of Pop in 1984 - after she spent all day trying to restore it to its original condition.
Taking to her Instagram account, the blonde beauty uploaded a photograph of her kneeling beside the star as she rubbed a damp cloth across the writing.
She captioned it: ''some people have no f*****g respect. i understand that there is a difference between the radio emblem and the record, but a name is a name (sic)''
Paris later took to her Twitter account to state that she had grabbed a bottle of acetone after her friend informed her that the star had been defaced with red paint.
She wrote: ''I was at my friend apt that lives basically next door this morning and another buddy of mine said he saw this last night. Thankfully there was a walgreens half a block away... justa bit of acetone bishhhh (sic)''.
Michael tragically died in 2009 from acute propofol and benzodiazepine intoxication but Paris has claimed she's always felt his presence since his passing.
Alongside a professional photo of the 'Thriller' hitmaker, she said: ''my one source of strength. the only thing keeping me going. my love, my light, my archangel. (sic)''
Paris' sweet words come less than a year after she paid a similar heartfelt tribute to her late father on what would've been his 58th birthday on August 29.
In an emotive caption, she wrote: ''birthday wishes to the love of my life, the one person who showed me what passion truly was, the one that gave me solid morals to live by and how to dream. i will never feel love again the way i did with you. (sic)''
Paris - whose mother is Michael's second wife Debbie Rowe - also thanked her father for ''the magic'' he gives her.
She added: ''you are always with me and i am always with you. though i am not you, and you are not me, i know with all of my being that we are one. and our souls will never change in that way. thank you for the magic, forever and always. (sic)''
