Her appearance may have coincided with Swim Week but Kendra Wilkinson didn't wear a bathing suit Saturday afternoon during her appearance at the Gansevoort South Hotel's One Group Lifestyle Retreat Lounge to promote her book Sliding Into Home, which covers her childhood, growing up as a tomboy, dabbling with drugs and eventually entering the Playboy inner sanctum.

Working a satiny floor-length maxi dress, the former Girls Next Door star was feeling a little paranoid about her baby weight. ``I'm still recovering from my 9.5 pounder,'' said Kendra, whose son was born last December. ``Big boy!''While most new mothers get to hide under tunics for a few months, the former Playmate is feeling the pressure to look svelte. ``There's been a lot about my weight out there,'' she bemoaned. ``My body fluctuates.''A national book tour hasn't helped matters. ``It's so hard to sit down and make a salad. I'm on the go. When I have fruit, I'll eat fruit, but when I don't, I have to eat. Right now I'm up on my gaining curve.'

Wilkinson, 25, can't really diet at home -- hubby, former New Orleans Saint player Hank Baskett, needs his calories. Even Hank Jr. is getting in on the act.

``One of his first meals was filet mignon,'' she recounted. ``He eats whatever we eat. We just put it in a blender and mash it all up. It's fun, like a little experiment!''

Kendra's bearing the brunt of all his good meals; the kid's almost 25 pounds.

``My back is hurting, but you gotta push through it,'' she said. ``You don't feel pain with your pleasure.''

Miami was the final stop of the tour, then she and Baskett leave Hollywood for Philadelphia, where he recently signed with the Eagles.

``It's been emotional,'' said Wilkinson, who will soon start shooting season 3 of her E! reality show Kendra. ``Meeting all my fans and having them thank me for my honesty. Very cool. Now we're ready for the next step.''

Psyched for the cheesesteaks?

``You know it! It'll be going in the blender. And I'll be eating that, too!''
