Jada Pinkett Smith calls husband Will Smith 'Captain Correction.'

The actress - who has two children, Jaden, nine, and eight-year-old Willow, with the 'Hancock' star, and is stepmother to his 15-year-old son Willard - says Will always thinks he is right and is forever pointing out people's mistakes to them.

She told TV show 'Extra': "I call him 'Captain Correction' because he knows everything. He's always correcting you on something. Some fact, or the way you pronounce a word."

Jada has also denied reports the couple have opened a Scientology school, insisting its curriculum is based on a variety of religions.

Jada - who is a devout follower of the controversial faith - said: "It's a completely secular school. We have Muslims, Jews, Buddhists - I don't discriminate against anyone."

Will and Jada donated $1 million to California's New Village Academy of Calabasas, where pupils are taught using several different teaching methods including 'Study Technology' - a learning method which was developed by the bizarre sci-fi cult's late creator L. Ron Hubbard.

It is also claimed at least six members of staff employed at the $11,659-a-year private academy are members of the religion.
