Burlesque dancer Katrina Darling, 22, has been offered deals for I'm A Celebrity... Get Me Out Of Here! and Celebrity Big Brother, the Daily Star reports.
Producers are apparently prepared to "break the bank" to get her as they believe she will be TV "dynamite".
Darling, who recently posed for Playboy, has never met the Duchess of Cambridge. Her grandmother is the sister of Middleton's great grandfather.
A source said: "They know she would be dynamite to secure. Kate might not be happy but you can bet she and the other royals will tune in."
A spokesman for Darling added: "We're considering a number of offers for reality TV shows."
