We're guessing Rihanna imbibes a few gallons of 5-hour energy drinks every day ’cause girlfriend just does not stop!
After getting in quite the thigh workout on Saturday, the popstar was back at it on Sunday, soaking up the adulation of fans outside her hotel in her floral print Christopher Kane sweats and Manolo Blahnik sandals before being whisked off to perform for yet another sold-out crowd at Twickenham.
A lesser person would've retreated to her penthouse suite and slept a full 8 hours, but not our RiRi!
Right after the encore, Miz Fenty changed into a glitter-bombed Stella McCartney top, distressed jeans, holographic Manolos and matching Stella McCartney clutch for some partying at Boujis nightclub with Cara Delevingne.
Do you think she and Rita Ora have worked out some sort of schedule for when they get to hang out with Cara?
Just wondering!

MADONNA!!!
Just as all the models were slipping out of their Stella McCartney Resort 2014 outfits, a dozen trumpets (slight exaggeration) heralded the arrival of Her Madgesty!
The living legend looked debonair in a black trench, collared shirt, and black leather gloves, swooping in to chat with the designer and even taking the time to pose with Steven Tyler.
Loves it!
We just hope her presence was appropriately appreciated and that those guys taking pics of her with their camera phones pass on this epic tale to their grandchildren.
It's a tale that can never be topped!

That's the best you got?
Julianne Moore may have been the center of attention at the DuJour magazine's summer issue party last night in New York City, but her outfit was far from attention-grabbing.
The 52-year-old redhead slithered into the Marlin Bar wearing a black snakeskin-print, long-sleeved Stella McCartney drop waist dress with black ankle-strap heels.
Granted, it was the same dress she was wearing to celebrate Stella's Resort 2014 collection earlier in the night, but we were hoping Julianne would change into a bright and sexy summer number that would turn heads.
Her wavy crimson locks were gorgeous as always, but the rest of her ensem was just the bore du jour!

Naomi Watts valiantly tried to make this Stella McCartney black lace jumpsuit work at the designer's Resort 2014 presentation in NYC on Monday.
It wasn't a total disaster, but overall it looked kind of off. Maybe a belt or different shoes would've salvaged it.
Hey, not everyone can wear the heck out of a jumpsuit like J.Lo!
But we'll give Naomi points for trying!
Thoughts???

Total twinsies!
Kate Bosworth nearly morphed into friend Stella McCartney at the designer's Resort 2014 presentation in New York on Monday night.
Her pale pink shift was literally cut from the same cloth as Stella's dress, but the resemblance didn't stop there!
Both women had that same beach-hair-don't-care tousled thing going on with their locks.
Think they planned it?
We wouldn't put it past them! LOLz!

Resort collections always have us dreaming of sunny climes and white-sand beaches, and we love them for it!
Despite the rainy New York weather on Monday night, Cameron Diaz defiantly attended pal Stella McCartney's Resort 2014 presentation in all-white.
The actress threw on a textured zip-front dress, styling it with strappy sandals, satin sash belt, and a purple faux leather wristlet clutch, all by Stella, of course!
The only thing missing from the ensem was some sort of pineapple and rum concoction!
Rain, shmain!

This angel brought back a piece of the blue sky with her when she fell from the heavens.
Seriously, look at Sofia Vergara's body! Incredible!
The 40-year-old actress wore an electrifying blue knee-length form-fitting Michael Kors dress to the Gordon Park Foundation Awards on Tuesday night in New York City along with a snakeskin Stella McCartney clutch and matching Brian Atwood shoes.
Her long honey locks cascaded perfectly as she posed with one hand on her hip for the red carpet festivities.
We're not a big fan of her purple and pink cuff, but when you're dealing with perfection, it's hard to find a flaw — especially when your dress is the color of the sky when the rain stops and the clouds part.
