And even though the B-day bash went down just one day before Snow White and the Huntsman's London premiere, K.Stew used every crafty skill she's got to dodge reporters' questions on the R.Pattz party at the A-list soiree.
So, how did Snow White respond when E!'s own Giuliana Rancic pressed the Marchesa-clad babe for deets on her BF's big day?
She spilled every friggin' detail!
OK, clearly, if you just believed the above sentence then we must give you a lesson in Kristen's personal life—gal's been dating Rob for years now, but the crafty Kris always stays coy on their relaysh.
And although we were desperately hoping Rob would walk the enchanting green carpet with his gal (the premiere was, after all, in London, Rob's hometown), Kristen stole the show in a stunning lace dress and Nike sneakers (after ditching her Jimmy Choos) and managed to stay totally mum on the whereabouts of her other half.
Cue the adorable back and forth banter between Giuliana and Kristen:
"Did you do anything special yesterday?" asks the E! News host.
"Uh, we did a junket yesterday," Kristen brilliantly tells E! News.
"I know, I was there," Giuliana counters. "But did you do anything last night fun while you're here in London?"
Uh, yeah ya did, Kris, but of course Kristen keeps all the juicy deets to herself!
"No I was really tired," Kristen says with a smile after a brief pause.
Oh, but Giuliana didn't stop there…"For a certain birthday?" she presses.
And with that, the crafty Kristen is literally rendered speechless! She turns away with a laugh as G quickly changes the subject.
So friggin' adorable! And let's face it, although Kristen drives us insane with her coy M.O., it's one of the things we love about the gal most. With all the crazy Snow White promotion, we're just so happy Kristen's work all went down in Rob's hometown—we know how much the busy duo loves their downtime together.
So, with that, we say Happy Birthday Rob and congratulations Kris!
Can't wait for this foxy couple to hit Cannes together.
