Your Shirtless Celebrity Roundup is Fab with Abs

The six packs are fearless this week, flexing underneath the summer sun thanks to a winter full of crunches and sit-ups. Whether it's Mark Paul Gosselaar tanning in a scene from "Franklin and Bash," or Kellan Lutz flexing for a photoshoot, we've got tummies that'll send ripples down your back.

It's no wonderKellan Lutz has one of the fittest celeb bodies, achingly gorgeous in its prefect muscle tone. And those abs! They lead right to a patch of surprising hairlessness. Pubic shaving has reached Hollywood, duckies.
Anti-bullying champion Ben Cohen continues his shirtless, pro-gay crusade with the cover of Gay Times. That's one furry ex-pro-rugby player torso we'd love to cuddle, if it weren't for the straight, married, with kids thing.
Ashton Kutcher was off to Rio for a photoshoot and some volleyball. Considering his fantastic shape, tummy crunches are certainly part of his Brazilian regime. Careful on the Pão de Queijo.
We've cheated by featuring Prince Harry with his shirt on. However...whoa! That is the most rockin' bod we've seen on royal since "The Little Mermaid's" Prince Eric. As he parades around the polo ground, his pecs and nipples are so delightfully clear, it's quite easy to image the smooth abs underneath. Don't know about you, but we're ready to ride that horse.
For you queens still bitter that het boy Kris Allen beat out flamegurl Adam Lambert, this pic might change your mind. Out on a camping trip, he goofs it up with some pals, flexing those abs. For pure sex factor, he gets our vote.
After working so hard on his pecs, Charlie Hunnam deserves to lie back and have someone admire his taunt tummy. We only wish it were a he, and the he were us!
