Is Drama from the Fantacy Factory older than his brother Big Cat?

You're likely thinking of Dappy from N-Dubz, not "Drama" from the Fantasy Factory.

Dappy is the younger brother of Big Narstie. There is no "Drama" from the Fantasy Factory. There was a show called "The Fantasy Factory", but that was a reality TV show, not a music group.

If you have any more questions about N-Dubz or Dappy, feel free to ask!
