Watch: Michael Jackson's son Prince says 'it's worth celebrating' the fact his father 'is the greatest'
Prince Jackson, 25, weighed in after Rolling Stone magazine labelled the One Direction heartthrob "the new King of Pop".
He was asked about it during an appearance on Good Morning Britain, and said that although Styles is "amazing", his dad really "earned" the title and in a different time.
"We’ve come in the situation before, Harry Styles is an incredible artist," he told hosts Adil Ray and Charlotte Hawkins.
"He’s got his own genre and he’s definitely an amazing artist.
"But, the 'King of Pop' was a moniker that really my dad earned in a time that the access to information and the access to popularity and fame wasn’t as easily accessible as it is today."
He continued: "With so many other social factors that you have to take into consideration at that time, I do feel that my father is the King of Pop, will always be the King of Pop, and it’s not something that you can ever take away, because we’ve just evolved so much as a society that those same factors will never be the same.
"So when you look at the… from where my father started to where he ended, versus where all these other people started to where they ended, it’s just night and day of a difference."
Late star Michael was also dad to daughter Paris, 24, and son Blanket, who is now 20.
The singer died in 2009 at the age of 50 following an accidental overdose of the anaesthetic propofol.
