That was quick!

On Sunday X17 photographers snapped these exclusive photos of Rob Pattinson leaving Kristen Stewart's Los Feliz pad, and not only was his red Chevy pick-up truck filled with clothes, bikes and suitcases, but he took the couple's dog too!

Rob and K. Stew got in a huge fight on his 27th birthday last weekend, and after that the two called it quits yet again. We're still not sure if it's for good, but a source tells Us Weekly that the drama started after Rob "blew off a birthday party planned in his honor by Stewart." The insider added, "All this stuff came up ... about the cheating, about how selfish she always is, about how moody she always is."

Rob stayed at K. Stew's home for less than an hour, and he then drove over to his pad, which is only a mile and a half away. We're wondering if he regrets buying a home so close to his adulterous lady vamp...

Twihards everywhere are mourning yet another breakup between Kristen Stewart and Robert Pattison, but hang on, kids -- it ain't over 'til it's over!

No doubt these two will get back together, but it'll take some time to repair their relationship after their big blowout Monday night on Rob's birthday.

As X17online reported exclusively, Kristen spent the better part of that day on the phone with Rob, arguing, and then crying to her friends. Rob zipped in and out of his house only once that day and it wasn't to see Kristen ... The two haven't seen each other since last weekend and all signs point to a split. And X17 told you first!

But here's the good part ... Kristen's finding comfort in pal and fellow Twilighter, Taylor Lautner. The actor has stayed close to Stewart to help cheer her up.

This isn't the first time she's found solace in her co-star; the two hung out at the batting cages back on March 12 with Rob was in Australia filming and Kirsten was lonely. The week before that, she caught a show with Taylor, taking in pal Marcus Foster's concert at the Troubador.

Is Taylor just Kristen's shoulder to cry on ... or something more?

It wasn't the birthday blowout Rob had expected ...

Pattinson and his on-again-off-again (on-again) girlfriend Kristen Stewart didn't celebrate the actor's 27th birthday together, they spent it in a heart-wrenching fight!

X17 photographers spotted Kristen at a friend's house Monday afternoon and the actress was in break-down mode over what appeared to be a possible break-up with Rob.

"Kristen was pacing back-and-forth in her friend's apartment, smoking. She looked really upset, talking on the phone for almost an hour -- I'm guessing she was talking to Rob. She was really animated, like she was trying to explain something. She was getting frustrated and seemed very emotional," our photographer tells us.

After KStew finally wrapped up the heated conversation, she and her pal drove to another friend's house and stayed outside in the street, in her friend's car, talking for almost 45 minutes.

Seems like a tense time for the pair. They celebrated Kristen's birthday just last month, partying with pals and all smiles. What happened? ... Could there be trouble in Twilight paradise?

She looked so glam at the Met Gala the other night, but K-Stew never stays girlie for long!

Kristen Stewart grabbed pizza with some friends in Hollywood the other day, and the Twilight actress was back to being her usual grungy self in a backwards baseball cap, hoodie, jeans, and sneakers. Someone needs to help her with her street style!

The brunette beauty does have a stylist, but that doesn't mean she always takes her fashion tips!

"Last season, it was so funny because they called us out in The New York Times [that] Kristen had sort of hit every trend last year except for peplum! She's not a fan of peplum. I tried with 20 peplum dresses this year, and it was not happening! I'm trying to get her to the high-neck turtleneck thing. I'm trying to push her," stylist Tara Swennen told StyleCaster about her client.

We can't understand why the Balenciaga spokeswoman prefers to ditch designer wares in favor of dirty duds!

Twihards, rejoice! Glamour UK has named Kristen Stewart the Best Dressed Woman for the second year in a row.

Our favorite human-turned-vampire stole the crown from the likes of Kate Middleton, Emma Watson, Emma Stone, and Taylor Swift, who rounded out the top five in the reader-voted list of "50 Best Dressed Women." True, KStew isn't usually dressed to impress, often donning cutoffs, sweatshirts, sneakers, and bed hair on her days off, but she dazzles on the red carpet. She rocked several sheer, fashion-forward Zuhair Murad numbers while promoting Breaking Dawn Part 2 last year. In fact, the magazine praised the Twilight star's go-to "rock-chick style."

The 23-year-old has endured her share of criticism in the past, but has always embraced grunge, laid-back chic.

"I go outside, and I'm wearing a funky T-shirt and my hair is dirty, and people say, 'What's wrong with her? She needs to invest in a hairbrush,'" Kristen told Allure Magazine a few years ago. "I'm like, 'Don't you get it? I'm not that girl! I never was that girl.'"

What do you think of Kristen's new title? The face of Balenciaga's fragrance Florabotanica is certainly blossoming into a fashion icon, but is she your pick for 2013's best dressed woman?

I guess Rob Pattinson doesn't mind the dirty hot look!

We caught Kristen Stewart hanging out with her hipster crew in Los Angeles, and the Twilight starlet ditched her uniform of Chucks and skinny jeans for a pair of shorts and slip-ons. Sexy!

While KStew and Rob were joined at the hip last week in Los Feliz, he's currently in New York City, and a several observant Twilovers spotted him at the Daughter concert at the Bowery Ballroom on Tuesday evening, where Katy Perry was also in attendance. But not to worry -- KStew's reportedly attending the Met Gala on Monday, so maybe she'll walk the red carpet with her beau? This year's theme is punk fashion, so we're guessing she has an amazing outfit picked out...

Would Kristen Stewart actually hang out with Rupert Sanders again? Would she possibly go back to the relationship that temporarily separated her from Robert Pattinson and broke up Sanders' marriage?

We snapped these exclusive shots of Kristen Sunday night at Malo Cantina in Silverlake -- the same place Rob took her last week to celebrate her 23rd birthday and the guy driving the car that took KStew and her pals home looks suspiciously like Rupert and the car looks like his black Acura!

After RPatz left town on Saturday, was Kristen getting lonely?

Kristen Stewart and Rob Pattinson have been snapped cruising around town in a beat-up blue Toyota pick-up truck, and even though she's got millions of dollars thanks to the Twilight franchise, she's definitely not spending it on a shiny new whip!

In the past K. Stew drove a pair of Mini Coopers, but after she was photographed cheating on Rob with Rupert Sanders in the front seat of her black Mini, she ditched the car and opted for something a little less flashy. Then again, half of Los Angeles drives Minis, and this ancient vehicle might be a little too obvious ... maybe she should go for a Honda or a Ford that isn't older than she is?

We're not sure if K. Stew is trying to avoid the paps or make a statement, but this is the girl who wears dirty Converse sneakers, dines at the same local spots and lives the simple life despite having a ton of money in the bank -- clearly she isn't materialistic at all! Over the weekend she was snapped at Malo in Los Feliz yet again, which is a cheap joint with 3/5 stars on Yelp...
