Kendra Wilkinson sends naked pictures to her husband to keep their marriage "fresh".

The former Playboy model - who has a 10-month-old son Hank with her NFL player spouse Hank Baskett - admits the couple have embraced technology to keep things sexy when their working commitments keep them apart for long periods of time.

She told People magazine: "We definitely keep things spicy even though we're not together in person. We know how to keep things fresh, romantic and sexy.

"There's Skype, yeah, that's definitely our number one. We also have our Blackberries. This morning, Hank woke up to a surprise text. Let me tell you, sending a naked picture to my husband definitely keeps him going!"

The 25-year-old blonde beauty believes their time apart makes her and 28-year-old Hank's marriage stronger.

She added: "You can take a breather and actually think about why you miss each other. Then when we see each other, we're fresh and re-energised and it's time to get it on again."

Meanwhile, Kendra has explained why she recently turned down the chance to pose for Playboy for a fifth time.

The blonde star hired a photographer to take some test shots but afterwards she sat down to talk it through with Hank and agreed she was making a mistake.

She explained to E! News: "Hank actually sat down with me and he went over the reasons of doing it. And, you know, my reasons weren't right.

"I wanted to do Playboy for the wrong reasons. The wrong reasons are to prove people wrong, not to prove it to myself but to people and to put my middle finger up to everybody and be like, 'I'm going to do Playboy!' But that wasn't the right reason, you know?"
