Pop star Justin Timberlake and his girlfriend Jessica Biel are addicted to word-making action game Scrabble.

The SexyBack singer and his actress lover spend many nights indulging their passion for boardgames instead of going out.

Biel says, "We do a lot of dinner parties and we play board games. I love Scrabble."

And the couple isn't alone in its obsession with the word game - other celebrity fans of Scrabble include Michael Bolton and Nicollette Sheridan, Robbie Williams and the Foo Fighters.
