Remember that E! interview where Vanessa and Ashley were asked if they'd do DWTS? Ashley said that she liked watching it, but Vanessa stayed silent. That's when I first started wonder whether she had been offered a place- so when she turned up to watch the final show my instinct immediately said she'd be on next season.
Then again, celebs usually go on shows like that when they need the publicity and I'm pretty sure that isn't Vanessa's case but I still think there's a very strong chance of her being on the show. If I had a few weeks free, knew I was a good dancer and someone was offering me tons money to dance I wonder what I would do??....Of course I'd do it! Who wouldn't??
