Kristen Stewart probably hasn't been too terribly worried about any of Robert Pattinson's leading ladies up until now -- but she may be squirming in her seat a little bit now that he's been cast in an upcoming film with the ever-so-sexy Scarlett Johansson. (RPattz & ScarJo? Oh MY!)

Yep -- it's true! Rob and Scarlett are set to star opposite each other in Hate Mail, but I'm guessing there won't be too much "hate" going on between the two of them on-screen, if you catch my drift. If anything, there will likely be a whole lot more lovin' than anything else. What would be the point of putting two major hotties together if they weren't going to hook up?!

By now, you've probably seen the sexy photos to come out of a recent photo shoot Robert Pattinson did with French Premiere magazine to promote his forthcoming flick, Cosmopolis, which is currently competing at Cannes. The pics are steamy, to say the least. Believe it or not, there are risque shots that didn't make it into the magazine. And there could have been more that were even hotter. That is, if RPatz hadn't been such a completely above-board kinda boyfriend!

According to a source who spoke with RadarOnline.com, the photographer had directed a topless blonde model to snake "all over his body, nibbling his earlobes, kissing his face and neck, and pressing her bare boobs against him." Apparently, Rob "did his best Blue Steel for the camera," but after a while, he got increasingly "uncomfortable."

Well, well, well. Looks like big tree fall hard. The Forbes Celebrity 100 list is out, and if you're a Twilight fan, you might be surprised who did, and who didn't, make the list. Who cares that Jennifer Lopez is number one and that Kim Kardashian is number seven, all we Twi-hards wanna know is where Robert Pattinson, Kristen Stewart, and Taylor Lautner fall on the list. It's our chance to see if the world is truly Team Edward, Team Bella (if that's such a thing), or Team Jacob, and folks, today we have our answer.

Drum roll please ...

Although the Fifty Shades of Grey flick(s) may be a ways off, we don't have to wait that much longer for sexy on-screen action between Twilight leading lovers Robert Pattinson and Kristen Stewart! Before heading off to Cannes, KStew appeared on the U.K. "chat show" (aren't their terms just so much more charming than ours?) The Graham Norton Show. Maybe it's because she has a thing for the Brits (obviously her BF is one!), but she didn't mind spilling on the steamier scenes we have to look forward to in Breaking Dawn: Part 2.

Apparently, the traumatic delivery of daughter Renesmee and transition to being a vampire doesn't take a toll on Bella's libido. Oh no, it has quite the opposite effect. For Edward, too! Kristen laughed while confessing to Norton that post-baby Bella is just as "randy" as she was before she becomes an undead mama.

Although Robert Pattinson and Kristen Stewart were most recently spied in the U.K., I'll bet they've made their way down to the South of France by now, because the Cannes Film Festival begins today! I know, when you think Cannes, you don't necessarily think Twilight. Nothing against the uber-successful vampire franchise, but it's just not the arty kind of film we tend to associate with the annual event. Nonetheless, the principle players -- RPattz, KStew, and TLaut, oh my! -- are all moving on and making flicks that are sure to take the famous film fest by storm.

Here, your complete guide to the Twi-Stars' exciting submissions to the Competition and flicks that will premiere at Cannes ... 

Even as Kristen Stewart attempts to move on and promote her new flick Snow White & the Huntsman, she's still getting bombarded with questions about Breaking Dawn: Part 1 (and Breaking Dawn: Part 2!). When she appeared on The Graham Norton Show in the U.K., he even got her talking about the now infamous "first time" sex scene.

Remember how blazing it seemed in the teasers and stills? There was the trailer showing Bella and Edward in bed! Complete with windowsill damage! We were convinced it was going to be so sexxxy. Rawr! But then ... when the film finally hit theaters last fall ... ugh! Major disappointment! It was not nearly as hot as we had hoped. So anticlimactic. Turns out, KStew actually felt the exact same way!

Yesterday, while Robert Pattinson celebrated his 26th birthday at Claridge's in London, getting A-list party on with preggers Sienna Miller and her hubby, who also happens to be RPatz's best bud, Tom Sturridge. But his rumored lady love Kristen Stewart was nowhere to be seen ... at least at one point during the party. So, of course, tongues were wagging today about her absence. Could this mean the two are on the outs? Or worse yet -- no longer an item?

Pffft! Don't make me laugh, people. This latest gossip is no proof that Robsten is no more. Especially since the June issue of Elle points to new proof of their love affair.

Welcome to Monday on The Daily Stir! Emily has a show you won't want to miss ... because, really, she's got the perfect cast of characters today. Kris Humphries wants Kim's engagement ring back, Robert Pattinson rumors are swirling, Beyonce and Jay-Z are in the news again, Glee is being put down by Bristol Palin (*wink*wink), and Mark Ruffalo is steaming mad ... or maybe we just want him to be. Enjoy!
