BEFORE: "It's tough for Lindsay right now," notes Flyweight-beat reporter for Celebrity Ring. "She desperately needs to withdraw and regroup...but fighting's her main income right now: she can't say no. And she's in freefall: girls are really coming at her full bore, and beating her like never before. Even in clubs and on the beach - Lohan's getting pounced more and more often by non-celebs - girls who wouldn't even of thought of trying her during her heyday. There's only one solution: beat Sienna. If she doesn't - there's plenty more hungry ingenues lined up behind Miller - all wanting their piece." Lohan in brightly coloured print bikini (teal; black; baby blue; white - all in curving/overlapping patterns); small white gloves; hair swept up into tidy battle bun. Sienna in pink bikini; shoulder length blonde hair loose; white gloves. Sienna cold-eyed, brazenly staring at Lohan during ring instructs: Miller pouring on the intimidation in hopes of cracking Lindsay early.

During R1: Lohan stiff-legged, left shoulder pointed at Sienna - left at hip, right at chest. Sienna hands up, palms out, stepping to midring to jab with Lindsay. Slender, stiff left hands stab back and forth - Lohan with a bit of an up-jab; Sienna chopping hers out from the high guard position. Girls extending on shots, mixing in long right hands: both standing up nice and tall, punching at offending faces. Clockwise rotation generated as Miller hooks Lohan's tits, then pivots left: Lindsay frowning upon receipt. Sienna making some money with a straight right reached in above Lohan's presented left hip: Linds grimacing, twisting a little to her right to take it. Both girls finding the other's chin via rigid right hands: good crisp stuff early. All even down the stretch when Lohan strikes: Sienna with her left fully extended, trying to ward Lindsay off...Lilo loops her right over top, jamming Sienna in behind the ear. Miller jerked to her right, stumbling forward, then clattering to her knees face-first in ropes. She's up at bell, woozy as Lohan beams brightly, jogging all jugs a-jumpin' to her corner.

R2: Sienna scowling, snarling: she hooks Lilo's jugs; pastes 'em a long right hand, pivots left while digging a swinging left into Lilo's bony ribcage. Lohan grimacing, jabbing: she taps at Sienna's cheek as Miller lashes another hook across those jugs, clapping 'em about. Elastic right hand brushes Lohan's lips - spooking her: she slides away with left hand extended, exposing her left-side ribs to a POUNDING straight right as Miller leans in. Linds cringing, moving to her right - she's jabbing to Miller's chest, pulling the hand back low as she circles away. Miller walking Lilo down, stalking her: she times one of those don't-hurt-me jabs - slings a bandy-limbed right over top, neatly kissing Lilo's jaw and turning her head aside. Lindsay's slender legs fold up, then straighten out, sending her stork-stepping to her right: she's a stunned beauty - extending her left to keep Sienna away. Miller lean, limber, scooting in off Lohan's left flank, pouring in another springy right hand over Lohan's left shoulder. Long punch pounds Lindsay's jaw at the ear joint: legs stiffen up, hands immediately drop to her lap as she pitches face first to mat! Sickening knockout - Lohan laying with hands under stomach, right cheek on canvas, lips parted, eyes shut: that's KO2 in bloodcurdling fashion - Sienna Miller.

After: Miller crowing, preening: she's not known for knockout power, but here she roars off the canvas to halt the once-feared puncher Lilo. Linds rolled to her back, gently brought round: she's down for a long time, raising concerns that she's no longer taking punches well. In days to come, Lohan's manager is FLOODED with challenges: Sarah Michelle Gellar looking to break her own slide; Nina Dobrev wanting to double up; Candice Accola wanting to show her wares; no-name ingenues from sci-fi shows and comic-cons...it's endless. Lohan in a terrible spot: openly hounded now by a classic Hollywood feeding frenzy.
