The Princess of Wales's former butler attempted to refute the 'myth' that EastEnders was Diana's best-loved show.
Burrell, speaking a month after the 15th anniversary of the royal's death, told the Huffington Post: "Brookside was her favourite and she met most of the cast.
"She went to the set of Brookside and got to know some of the cast very well, especially Dean Sullivan, who played Jimmy Corkhill on the show. He became a friend, who she regularly telephoned."
Regarding the princess's supposed thoughts on EastEnders, Burrell commented: "Maybe in the very beginning she did tune into it, but it wasn't something that she would want to watch regularly."
The 54-year-old, who last grabbed the public's attention during his stint on I'm a Celebrity... Get Me Out of Here in 2004, also spoke candidly about his friendship with EastEnders actress Barbara Windsor.
"When Barbara Windsor first joined EastEnders, she used to read bedtime stories to my boys at Kensington Palace. She used to come to see my boys when they were about 10 and 7," Burrell recalled.
"They were fully aware of who she was. She's charming. Barbara is still a good friend of mine. We've had a lot of fun."
