Because usually they're so minging, y'know?
We're having a great time with all this Water For Elephants shizz - Robert Pattinson is striking a pose at every possible opportunity and looking HOT; Reese Witherspoon is making us ever-jealous of her incredible outfits, and...Christoph Waltz...is sometimes there too.
The film is out in the UK TOMORROW (May the 4th be with you), and the stars rocked up to the Parisian premiere this weekend. Reese looked stunning in a red, one-shouldered Giambattista Valli frock, and R-Patz looked like he'd been dragged through a hedge backwards by a crazed Viking on an angry rampage.
If that kind of thing makes someone look really fit.
