Before: Meester livid at Snow guest-starring on GG - Snow just as delighted to be in Meester's hair again; on-set fight a foregone conclusion. "I'll never stop hounding her," determined Brittany says. "She never dreamed I'd get onto her show to bring the fight to her doorstep. Getting Leighton beat on her own set is just going to be SWEET!" Meester so determined to crush Brittany, Leighton arranges for a formal FCBA sanction on the fight. "It won't be televised of course," Leighton reveals, "wrap-party fights rarely are. But I wanted it to cost Brittany. She needs to be regretting this little decision of hers, and hanging another L on her is the perfect ointment for this mosquito bite!"

Leighton in bright green neon bikini; small black gloves. Snow in bubblegum pink bikini, small white gloves.

During R1: Leighton tight-lipped, stone-faced as she punching into Brittany left-lett-right: Snow's head punched aside as Meester leans into a chopping cross. Leighton forward, hop-hooking Brittany's tits; swift right cross turns Brittany's head aside again, driving her to ropes. Meester into Snow's gut via plugging right hand: Leighton shifts weight to right foot, claws her hook across Brittany's breasts: Snow's wide eyed with shock. Middle minute: Leighton squares away, extended hands to knuckle Brittany against ropes: brunette wants to be methodical, stabilizing blonde for body work. Brittany grimacing, covering up earmuff: sturdy little body jumping and quivering under Leighton's brisk touch. Tummy, ribs, flanks - Meester in their digging, snatching the mitts off hated blonde beef, pushing Brittany back into position as Snow's rolling and bending. Good scrubbing beatdown - Leighton to Brittany: Snow discouraged, blinking back tears en toute to her corner.

R2: Leighton leads the double-left hand, misses the right over top: Snow slips low, hooks Leighton to ribs, then trades hectic rights and lefts as girls brawl toe-to-toe. Leighton's knees bend as she chin-clipped: she backs off, spitting jabs; Snow weaves her way forward. Hopping hook Snow to Meester puts Leighton ropes: Brittany plows in left-shoulder-to-chest, crushing Leighton to cables. Pumping hup-hup downstairs: Leighton bunching up, gurgling in pain as Snow shows her strength. Compact blonde in there digging, bumping shoulders, keeping Meester pinned down. Leighton grimacing, clipping little right uppercuts inside...trying to use her left shoulder to bump Snow off. Brittany shaking off Meester's effort: blonde's entire world consists of Leighton's hips, tummy, ribs and breasts - blonde fists just busily getting after the goods. Bell: Snow panting, but grinning happy: Leighton's turn to snivel and scowl, looking scuffed and abused through 2.

R3: Leighton: long left jab finds Brittany's mouth; step-in short left uppercut finds Brittany's chin; short right uppercut finds blonde chin and Snow staggers back all how-could-you eyes. Leighton snarling - stoop-lunging in to spear jab-to-belly: Snow backpedalling, hits ropes hard, covers up grimacing. Leighton pouring into Snow: swinging right to paunchm, biting left to paunch..brunette lowering left shoulder, nudging her blonde upright. Hook takes Brittany to paunch, then Leighton dips left shoulder, pops hips-right and fits a sweet left uppercut snug to solar plexus. Snow shouts in pain - mouthpiece spitting off her teeth to slap against Leighton's breasts: sturdy blonde stricken off a pinpoint plexus shot. Meester enflamed - feeling her foe's distress: Leighton widens stance, lets her hands go in blazing array. Snow sitting in ropes, trying to cover up: Leighton seething, teeth bared - just hustling straight left/right criss-cross patterns into Snow's crumbling guard. Terrific pasting - Snow facing helplessly into the brisk whitewash - ref jumps in to save her as Meester begins scoring cruelly. TKO3 in satisfying fashion - Leighton Meester.

After: Meester puts her foot down - turning back a brazen challenge on her own turf by her peskiest rival. Cast and crew applauding whether they like Leighton or not - it's a pretty impressive performance for a little brunette slickster. Leighton taking a blubbering Snow for a delicious little walk - Brit snivellling, well-rebuked; Leighton preening, guiding Snow about the ring with the right hand round her hips. Snow's woes extended - she's said to be considering offers from Minka Kelly and other Sophia Bush size bantams in an effort to shake her slump. Leighton breezy in days to follow, dropping names like Sarah Michelle Gellar and Kristin Kreuk as being on her personal to-do list.
