Jada Pinkett Smith sends husband Will Smith saucy pictures to keep the spark alive in their marriage.

The actress - who has been married to the 'Men in Black' star for 12 years - says the couple still enjoy a healthy sex life as they make a huge effort to keep it interesting.

When asked by Oprah Winfrey on her talk show how they keep the romance alive, Jada replied: "Keep it spontaneous. I surprise him. He's a thinker. He's always thinking. I just, I always surprise him.Now I don't know if you want to get in on how I surprise him.

"During the day I might send a sexy picture of some sort.If he's on set with me, we might take a break."

While the couple have a very healthy love life, Will - who raises three children, Trey, Jaden and Willow with Jada - admits he is still insecure when it comes to money issues, despite being very wealthy.

He said: "No matter how successful you get, it's really difficult to shake your mindset. I still have a poor person mentality. I can't shake it and it gets really detrimental. It's really difficult to shake. When I go to sleep at night right now, I'm as financially nervous as I was 20 years ago."
