What Jada Pinkett Smith Considers Foreplay With Will Smith

Dec. 31, 2014— -- After 18 years of marriage, Will Smith can't take his eyes off his wife Jada Pinkett Smith.

That alone is motivation to work out, the 43-year-old actress told the January-February issue of Shape magazine.

"When my husband of almost 20 years can’t take his eyes off me? That’s amazing," said Pinkett Smith, who maintains her killer body by stair climbing and reps. "But the number one reason I go to the gym is because it keeps me sane. It gives me a place to exert energy, frustration, sadness, happiness, and joy."

It also keeps the petite actress at a trim 108 pounds.

But just because she's small, doesn't mean she thinks that way.

"It’s an internal thing," said the star of the Fox series "Gotham." "I know that I’m petite but I never think like I am, ever. The truth is, there are times when I feel as big and tall as Will!"

Pinkett Smith also exercises her mind and spirit with daily morning meditation and prayer. "It’s the best way for me to get my energy and my brain focused and in alignment for the day ahead,” she said.

She shares a love for spiritual and self-expansion books with her 46-year-old hubby.

"It’s a big turn-on for me to be spiritually and intellectually challenged by Will. To me, it’s like foreplay!" Pinkett Smith revealed to Shape. "Of course, I enjoy that I have sex in my relationship, but I think this other intellectual aspect is quite unique and something that strongly connects us."
