Will Smith feels "lucky" to be married to Jada Pinkett Smith.

The 43-year-old actor believes the key to his successful union with the actress - who he tied the knot with in 1997 - is the fact they always support one another and he particularly admires the way his spouse always remains calm under pressure.

He said: "What's helped us is being supportive, no matter what the situation is. I'm so lucky to have someone like Jada. She's really an incredible woman, wife and mother.

"She is just absolutely hardcore, like she absolutely is unfazed by the weight and the pressures of life. She is so calm and cool and easy in any situation. She can bear anything, and I just love that about her."

Will flew back to Los Angeles from New York almost every weekend while filming 'Men In Black III' to be with Jada, the couple's kids Jaden, 13, and 11-year-old Willow, and Trey, his 19-year-old son from a previous marriage, because he says he and his wife always put their family first.

He added to People: "We make the effort to always put the family first. Being there for each other and being present with our kids is the most important thing. I take being a parent very seriously."
