BEFORE: "I'm an overwhelming challenge for poor Mila," Sienna sympathizes in prefight. "I'm wiry and fast, plus I'm taller and more attractive: just stepping into the ring with me diminishes her. I'll have her out in three, lads: depend upon it!" Kunis plucky, determined not to be steamrolled by the new wave of cocky UK fighters. "Sienna's never done anything in the States," Mila says. "I know for a fact she's trying to navigate around girls her own height, so she's not nearly as confident as she sounds. She may be taller, but I know I'm tougher: I'm gonna drag her out back the woodshed and tan her ass!" Kunis in tan, western motif bikini with fringes; small glack gloves; tan boxing moccasins to the knee; indian head band holding hair off her face. Sienna in white bikini with ring connections; fluffy white-fur boxing moccasins to mid-calf with big fur pom-poms dangling; small white gloves.

During R1,2,3: All-action rounds as Sienna gives up her height to indulge in batting, slapping two way lather. Exchanges usually develop as follows: Sienna scoring jabs as Mila crosses arms, scoots forward in bobbing crouch; Mila gets inside, begins wide, slapping assault, scoring against Sienna's sleek flanks/perky tits; Sienna begins giving ground - putting weight on right (back) leg as she bats back at Mila - Kunis eventually pressuring Miller ropeside; clinch - ref's break restarts 'em midring. Hard to score: Mila's gutty determination IS driving Sienna to ropes, but there's no question Kunis is catching the harder clout in the exchanges. Sienna proves able to hook with leverage off her right leg - frequently turning Mila's head aside. Kunis mostly just arm-punching and slapping: the occasionally biting blow leaves a mark on Sienna's pristine torso, or turns her chin aside. Frothy, fast-paced action pretty enough to watch; energetic - but Miller's trainer's had enough of the senseless wailing after 3.

R4: Sienna making a conscientious effort to employ her boxing. She widens stance; right heel up off canvas; pumps jabs with stiff vigour, finally denying Mila easy access. Kunis a trooper - initially trying to bob past the jab in her crossed arm stance: Miller too rangy/leggy, manages to turn her girl and maintain distance. Latter half the round - Sienna's constructing good opportunities with her footwork - setting up just right of centerline on Mila, fitting straight right hands down the pike. Good tart spank on these rights: fully extended blows; Mila's head jolting back; Mila's face showing discouragement for the first time. Sienna's overall output drops, but her effectiveness greatly enhanced by various measures taken.

R5: Sienna back at Mila with drilling jabs - rotating clockwise while poking Kunis into compliance. Mila adopting a raised earmuff guard to block stick: pretty brunette face scuffing up badly at this point. Sienna's shafting rights blocked as well, but she's finishing up smartly with a licking left hook across Mila's tummy. Wincing pain from Kunis as she cuddles herself, backs off cranky with Sienna walking her down a-smirking.

R6: Sienna having it all her own way now: Mila's spirit is broken - feisty brunette no longer throwing herself willy-nilly at her blonde. Well outside, Sienna pumps poke at leisure - picking apart Mila's defences; dropping in the odd arrow-straight right to knock Kunis' head back. It's all too much: steady tap-tap-tap of Sienna's cruel fists finally unhinge Mila: Kunis covers her face, turns her back on Sienna after eating a stiff right hand. Miller jubilant - she swings a left wide, looping it around to try to punch Mila's face from behind as blonde falls in. Embracing Mila from behind, Sienna lifts her right knee into Kunis's jumpy little buttock, then pushes her face-first to ropes. Mila sobbing out, cowering face-in-gloves, chest-first against ropes: Sienna at her back, flapping away with wrap-around blows. No real damage being done, but Mila's non-combative posture gives ref now choice. He stops the fight, cuddling blubbering Mila to safety as Sienna struts away hands held high. TKO6 Sienna Miller.

After: Tale of 2 Siennas: early on, lack of discipline saw her basically slap to a standstill with the smaller girl; settling into boxing mode, Sienna clearly dominated with skills to rival Penelope Cruz or Naomi Watts. "I was over-excited," Miller contends in postfight, aware of her performance swings. "I wanted to show that I could simply stand and slug with her - and I hurt her frequently from that posture, but I was giving her too much show in the bargain. Once I straightened out, she was helpless against my class: as I imagine most of the women in this division would be."
