The couple held a lavish cocktail party at the London Hotel last weekend to celebrate their forthcoming nuptials, and challenged each other to see who is best on the dance floor.
A source told People, 'Nick and Vanessa gave heartfelt toasts and got a little choked up. Nick talked about the journey they've been on and how much it meant to have friends and family celebrate with them.
'Afterward there were some serious dance competitions throughout the night, which were hysterical! That's Nick and Vanessa's thing.'
