4. Catherine Zeta-Jones

Famed A-lister and one of the most beautiful women n the planet, Catherine Zeta-Jones was only 15 years old when she dropped out of Dumbarton House School, in Swansea, Wales.

Packed with talent and passion for the arts, Catherine decided that Dumbarton was not what she wanted so she moved to London where she attended The Arts Educational School.

You could say that the actress fell in love with acting after performing for the local theatre circuit, and from that moment on, nothing could stop her from achieving her dreams.

That dedication led to her huge break in Les 1001 Nuits in 1990 (when she was only 21), but it stopped her from achieving an official high school diploma.
