The 44-year-old star plays fashion designer Camilla Marks in "Empire" and her character's love interest Hakeem is 20 years her junior.
Campbell is adamant it's "not natural" to her, as she does not date younger men in her actual personal life, reported Female First.
"(Camilla) is in her 40s, she likes young guys. I don't date younger men so it's not natural to me. Hakeem is younger than my brother.
"I don't like that word (cougar). It's not that big a deal, it's just a word. But I'm from London and it's not a word we associate with and say very often is it?" she said.
