"Party for Two" is a song by Shania Twain With Billy Currington which is a duet, where Shania entices a guy to come over for a party. He resists at first, but when she makes it clear that the party will be just the two of them, he finds the idea more appealing. Twain wrote this with her husband Mutt Lange, who is a very successful producer. Twain, who was known as a Country singer, became a crossover star with the help of Lange, who added a Pop sheen to her songs. They were married from 1993-2008.
