Before: Moore the latest in a long line of big name celebs stepping onto the beach to get their grooves back - Jenny O'Dell at ringside isn't sure she likes it. "On the one hand, it's bringing a lot of exposure to the sand - look around - this is a huge crowd, but Demi doesn't need to be here. She could fight under Theron/Hurley with just a phone call, but she's here because she's on this personal youth-kick what with the plastic surgery and her MTV fans. I think it's a little Hugh-Hefner pathetic if you ask me - Demi's way too old to be true beach. I'll tell you something - if she thinks she's going to showcase on Katie - she's got another thing coming. Bosworth can flat out fight and I'd love to see her stick it to Demi today." Moore with the straight black hair, burgundy bikini, Kate with bikini top in pale blues and whites splash print, navy surfer-chick bottoms. Beach n' Bleachers set up So. Cali. beach.

R1: Demi right at Katie, gets a dose of her own medicine as Bosworth meets her head on and goes to work. Kate elbows in, right hand at her chin, left at chest height, relaxed - she's getting off with crisp, easy action, beating Demi to punches and keeping the brunette on the defensive. Bosworth chiselling the jab, getting Demi's hands up: blonde goes body with swinging hook to the kidney or chopping right hand to the waist, bumping left shoulder to step the brunette back. Demi against the ropes, grimacing, trying to block and roll but not countering - Kate just staying on her, putting tic-tac-toe combinations on Moore, scuffing up her face, working the million dollar body like it's on sale. Demi gritting her teeth and slugging back to avoid the shutout, but she gets a rude introduction to the beach as smiling Katie B takes the points.

R2: Demi business like, stepping in close with her jab, leaning forward to carry the right hand into Katie's breadbasket, then leaning right to hook stout blonde ribs. Kate right back at her: insolent little left uppercut on the teeth, hook in the ribs, or bouncing that hook off the body first, doubling it up to clout the ear. Midway through, girls banging body and turning on tight right hands up top - Bosworth wins the race and DEMI GOES WOBBLY BUTT! Moore shocked off a short right, goes to an ear muff guard as she stand flat-footed - Katie takes what's offered. Hook, hook, hook to the ribs, left uppercut between the mitts - Demi punched out of her defense staggers back, sets up hurt at the ropes. All Bosworth down the stretch as she jabs her way in close, puts tight, tough dukes to firm brunette belly, then works those gorgeous jugs without respect. Moore ashen faced, trying to wrap up on Kate - Bosworth rotating her shoulders, lifting her mitts up and into the offending rack, pounding puppy to the bell.

R3: Kate back on top with that harassing, pesky, busy assault - left hands clipping uppercuts, digging hooks, right hands chopping at cheek, swinging to the ribs - Moore giving ground - brunette looks shopworn, harried as she retreats around the ring. Second minute - Moore getting pelted at the ropes, dips and digs a veteran low blow square to Katie's trunks - blonde bunches up with a groan - ref jumps in - Bosworth gets a moment to collect herself but it's Demi who benefits. Moore moving to midring, working behind her jab - Bosworth matching her step for step, like mirror images the way the girls get into position to bang short, snapping punches off one another. Demi finally stacks her girl up, refusing to give any more ground - heartless two way slugging brings the crowd to it's feet at the bell.

R4: Kate still wincing from Demi's trunk check - Moore takes advantage. Good stiff jabs from Demi, stepping Katie back to the ropes, then Moore goes body with the swinging right hand below the elbow, matching rip from the left to the liver. Kate hustling back up into Demi, flurrying her foe's breasts, but blonde's on her heels, sitting in the ropes - she can't back Moore off. Demi really pouring it on, dig-digging at Kate's youthful waist and flank, shaking the blonde, bringing uppercuts tough to the chest and chin, shoving and shoulder-bumping to keep Bos off balance. Midway through, girls trade hooks and Katie goes limp - DEMI UNLEASHES! Moore with a free pass - Katie stunned, helpless, hands in her lap, she sits pretty for a pasting as Demi helps herself to beautiful blonde face. Katie out, sagging to her right as punches bash her skull back and forth - ref very late in making a move as Bosworth finally slumps to the canvas out. Demi bundled back snarling - she's the KO4 victor.

After: Kate giving Demi a nasty surprise early on - veteran looked slow, sluggish in the first three as nubile blonde put a beach-style beatdown on Moore. Demi not as greasy quick as she used to be, but she's got those heavy hands from punching lightweight bodies all these years - when she got to Katie, Katie stayed got. "I love fighting outdoors!" Moore says, tossing her head like a kid, adoring fans shouting her name - Jenny O'Dell ringside, tongue in cheek, arms crossed - she's less than impressed.
