Nathan won through to the finals of BBC1's Strictly Dance Fever after wowing the judges and the voters with his performance last weekend.
Nathan, 26, performed an 80s jazz routine to the theme tune of Fame with dance partner Kirsty.
The couple are currently holed up in a mansion, along with nine other couples, polishing up their routine for Saturday night.
On Tuesday night, Nathan got to dance live on BBC 3 with childhood dance heroine Bonnie Langford.
He had written to Jim'll Fix It when he was a youngster asking to dance with Bonnie, but his dreams were never realised — until Tuesday evening.
One couple will be evicted from the house tomorrow after all 10 couples perform live.
And Nathan, who teaches dance at Stagecoach based at Ocklynge School, is hoping that Eastbourne voters get behind him again to keep him on the show, hosted by Graham Norton.
Strictly Dance Fever is on BBC1 at 5.55pm tomorrow.
