Jennifer Love Hewitt wants to show her sexy Maxim spreads to her grandchildren.

"It's nice to have the Maxims of the world out there, because you can look at them when you're 80 and be like, 'See? No, really, I was cute, I promise!" she tells the May issue of the mag.

She also explains why she may have fallen for comic Jamie Kennedy.

"The two biggest things [I look for in a guy] are bring trustworthy and funny. Humor doesn't fade," Hewitt says. "If you're a funny person, you will always be a funny person. You're not just going to wake up one day and be like, 'I'm not funny anymore.'"

Hewitt -- who split from her fiance Ross McCall last December -- also says she's "all about geeks.

"They're funny, so that's a big plus. Also, geeks are really humble," Hewitt says. "They don't have to be the person in the room with the coolest shirt."

Hewitt costars with Kennedy on Ghost Whisperer -- and says people often think she can talk to dead people just like on the show.

"At the grocery store, getting cough syrup at the drugs store, wherever. I'll have people come up to me and go, 'Listen my grandmother just passed away, you've gotta help me!" she says. "I'm like, 'I'm just getting lettuce. I can't help you!'"
