Jenny recently fronted the men's publication for the sixth time at the age of 39, and Kendra - who has appeared in Playboy on a number of occasions - believes the blonde beauty should be proud of what she has.
She told People.com: ''Good for her. She definitely has it, why not flaunt it. If that gives her confidence at almost 40 years old, why not do it?''
Jenny - who was the 1993 Playmate of the Year - recently revealed she was not worried about her 10-year-old son Evan seeing her nude pictures because he would be able to find much worse on the internet.
She said: ''I think he can find a lot worse available on the Internet these days.
''I think people make such a big deal sometimes about it, when I feel like it just comes down to how you raise your child and how you explain things to your kid.''
However she revealed she did not put them up in her home.
She added: ''I don't have one magazine cover up, period.
''I mean, I don't even have my Rolling Stone cover up. It's like, who wants to look at themselves? I don't.''
