Kendra Wilkinson Kendra Wilkinson

Not only have reality TV Girl Next Door-turned-mommy Kendra Wilkinson and her husband, NFL wide receiver Hank Baskett, just taught their son, Hank IV, to high-five, they definitely have something to high-five about: Kendra's autobiography, Sliding Into Home, made the bestseller list.

"We are so excited because we found out that I made No. 4 on the New York Times bestsellers list!" the E! star told TV Guide Magazine when the couple attended the ESPY Awards.

Wilkinson is still wrapping her head around her durable popularity, which hasn't been dimmed despite her wild past as one of Hugh Hefner's trio of live-in girlfriends and the recent surfacing of a sex tape from her teen years. Since the book debuted, she's learned just how closely her fans identify with various periods in her personal life, controversy and all.

"Honestly, it's like a therapy session when they come to meet me," she says. "They circle their favorite chapters and they say, 'This is what relates to me in my life, and thank you so much because I survived all that.' That's why it's so easy to talk about. People are like 'You lived a crazy life — do you regret it?' I'm like 'No!' Because if it wasn't for everything I experienced, I wouldn't be here with my husband and my son. I mean, I lived my life. I'm 25 and I still have a lot to live, but I lived a crazy teenage life, on through the Playboy Mansion years."

Along with celebrating the book's success, Wilkinson is also thrilled with seven-month-old Hank IV's new high-fiving ability — though her husband is slightly less enthused. "All I'm hearing from the other room is 'High-five! High-five! — Yaaaaay!'" laughed Baskett. "That's all I hear, all day long."
