Will Smith says the secret to a happy marriage is "lots of sex". The 'Hancock' star - who is married to Jada Pinkett Smith - insists a healthy sex life is the key to a successful relationship.

When asked how he keeps his 11-year marriage fresh, Will replied: "Lots of sex. All the time, every day. Just lots of sex keeps me going good!" Will also revealed it wasn't until three months into his relationship with Jada - the mother of two of his three children - that he realised she was the one for him.

He added to FOX News: "I was very interested that first night, but I was in a bizarre mental space. Three months into it we were at her mom's house and it just hit me. I looked at her and just knew this was it." The 39-year-old actor recently revealed Jada must be prepared to have "lots of sex" if he decides to take a career break.

He said: "I've been working a lot the last couple of years. My wife has said we have to take the next five months off. I enjoy my job, I really enjoy working. She might need to be prepared to have lots of sex!"
