Unfortunately, when it comes to John Travolta, it's not him doing the mentioning. The Saturday Night Fever star was approached to do the show but politely declined because of "daddy duties." Well, you can't fault him.
As for Danny Gokey, the former American Idolstar is campaigning himself to get on the big show. He's not only hoping to lose weight by competing, but also show Simon Cowell that he's not a terrible dancer.
Also hoping for a shot? Paul Byrom, an Irish singer-songwriter who is using his Twitter fanbase to push for an appearance on DWTS. Considering he isn't very well known though, we wouldn't hold our breath waiting for his appearance.
