Just Dance 2 is now the bestselling third party Wii game, according to publisher Ubisoft.

While exact Just Dance 2 sales figures weren't provided, the company said in a statement that the currently Wii exclusive franchise has sold 14 million units to date worldwide.

"Ubisoft is incredibly proud of the monumental success Just Dance 2 has had the past nine months," said US president Laurent Detoc (via Gamasutra). "The game's outstanding performance solidifies the Just Dance brand as a pop culture phenomenon."

Ubisoft launched Just Dance 2 Extra Songs for Wii in the UK today, and plans to take the franchise multiplatform with Just Dance 3 - which will support Kinect and Move - this October.

Just Dance 2 came in at No.10 on June's US sales chart.
