Hughton spent three years as Jol's assistant at Tottenham Hotspur before the Dutchman was sacked in 2007.
"There are almost two sides to it, because I am a really good friend of his, but also a rival manager," said Hughton.
"When it came out we were playing Fulham on the first day, of course it is something you have a laugh and a quick joke about.
"But just because he is a good friend of mine does not make any difference - we will want to win and do well in the game against them as much as we will in any other game."
The Canaries travel to Craven Cottage on Saturday.
