Will Smith has a "stash" of saucy photos of Jada Pinkett Smith he's taken while she's been sleeping.

The 43-year-old beauty has posted an intimate snap of herself on Facebook in which she's lying in bed without clothing, and the actress revealed she's only just learned her 46-year-old husband - whom she married in 1997 - has a library of pictures of her.

She wrote: "I discovered the sexiest secret the other day.

"My husband takes pics of me in my sleep. He has a whole stash he revealed to me and I really enjoyed getting a glimpse of myself through his eyes.

"I had to share one with you guys. Life is art. Life is beauty. (sic)"

The couple - who have two children together, 16-year-old son Jaden and 13-year-old daughter Willow - recently revealed they strive to spend quality time together in order to keep their romance alive.

However, Jada says rather than going on a date to a plush restaurant, they prefer to bond at home.

Jada - who is set to star in 'Magic Mike XXL' - told Health magazine: "A lot of times, we'll do it [have a date] at the house because when we go out it can be a little hectic.

"We have different places around our yard where we like to set up a little Arabian tent, pillows, wine and cheese, candlelight. Will likes really thought out productions."
