Cox: Smoking keeps me thin

Courteney Cox has put her slim physique while starring in 'Friends' down to her smoking habit.

The actress played high-maintenance Monica Geller in the hit US show, which ended in 2004.

Courteney and her female co-stars Jennifer Aniston and Lisa Kudrow were famed for their svelte physiques, but the 45-year-old insists she wasn’t actually that healthy.
