We love a good celeb feud, don't you? Especially when an ultimatum is involved!
Nothing like giving somebody an outrageous demand to really get the pot boiling!
If you've been following the Rihanna/Cara Delevingne/Rita Ora saga, you know things just continue to get juicier and JUICIER!
Cara keeps bouncing from RiRi to Rita like a shuttlecock in a vigorous badminton game, and now it looks like Rihanna's had enough of the back-and-forth — she wants the Burberry model all to herself!
A source explained:

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!

With thighs like hers, you'd wear thigh-high boots all day long, too!
Rihanna continued to terrorize the streets of London with her fabulosity over the weekend, exiting her hotel in epic style on Saturday.
The singer kept her weave dry with a Maison Michel cat-eared PVC hat and stayed warm in a Trapstar quilted jacket that featured a cute little kangaroo pocket.
But her Rihanna for River Island thigh-high lace-up boots were the main attraction! And, of course, they're completely sold out already!
The night before, RiRi hit up the Cuckoo Club with bestie Melissa in a Trapstar white t-shirt dress with zippered openings at the sides that showed off her black booty shorts and printed Tom Ford thigh-highs.
SAUCY!
Which thigh-licious outfit is UR fave???

Rihanna walked directly into the warm embrace of screaming fans as she stepped out of her London hotel on Friday.
Princess RiRi was apparently headed to Harrods for a shopping spree, but we can't imagine what she could possibly need to buy now.
The girl has EVERYTHING, and we rarely see her wear the same thing twice!
Regardless, Rih adorned herself with casual-luxe fare for the dough-dropping trip, including a Chanel cuff, the yellow lego purse she got when she was in Paris and Comme des Garcons Converse sneakers!
That black button-up dress is one of the most conservative things we've seen her wear while in Europe.
Isn't it a bit jarring to see her so clothed lately?!

Rihanna's first ad for her MAC Cosmetics collection has been unveiled for our viewing pleasure, and it's SUBLIME!
The simple shot features the 25-year-old wearing expertly applied RiRi Woo lipstick with the red theme extended to her glossy long nails and silky headscarf.
All the pieces, including a lipstick called Heaux (LOLz!), will go on sale on the MAC website on June 18th, and you better be quick with those typing fingers, because we have a feeling everything will sell out just like the first time!
We hope the peeps at MAC are ready for the onslaught! We wouldn't even be surprised if their site crashed!

Rihanna is still rocking the heck out of Manchester!
After performing for a sold-out crowd of 65,000 peeps the night before, the pop powerhouse stepped out of the Lowry Hotel on Thursday looking like your average gorgeous Barbadian in England.
RiRi was more covered up than usual in distressed jeans and a Natural Born Killers tee with Woody Harrelson's shaved head front and center.
But, of course, she had her designer faves on as well, including Saint Laurent heels, Givenchy sunnies, and that Christian Lacroix choker Chris Brown gave her last year!
Guess she didn't pawn it after all.

Prepare yourself, Manchester!
After making sure to get the most out of her Paris trip, Rihanna hopped across the English Channel to visit the Brits.
The 25-year-old once again showed off her styling prowess while out to dinner at San Carlos restaurant on Tuesday, looking like the coolest of the cool in a denim trench and red pencil skirt, both by Miu Miu.
We just have to stand up and applaud the brilliant mix of texture here — soft cotton, patent leather, denim!
Top it all off with a messy bun and scarlet lips, and RiRi's got herself another street style win!
