When you're an actress dating a famously purity-ring-clad pop singer, how can you out-chastity him? If you're Camilla Belle, and your beau is Joe Jonas (of the Jonas Brothers, squeeeee!1!!), you go to great lengths.

Pop-country tween phenomenon Taylor Swift dropped by Ellen today to promote a new album of songs that tap deep into the wells of heartache she's already amassed in her scant 18 years on this planet. The most achy-breaky of all? Her breakup with dreamy-haired Jonas brother Joe, about whom she says pragmatically, "One day...I won't be able to remember the boy that broke up with me over the phone in 25 seconds when I was 18." What follows is a thunderous wave of "Ohhhhhhwaaahhhhhhwhoooooooaaaa" from the audience we think is supposed to encapsulate their shock, sympathy, and outrage over the callous tele-dumping. While we feel for the singer, we too are certain there's far more worthy suitors in her future, and she'll chalk this experience up to yet more grist for the country-song mill, culminating in a CMA-winning composition entitled, "I Need Your Lovin' (Like I Need A Fartin' Dog in My Dodge)."

Heading into Sunday night's VMAs, one could never have predicted that the Jonas Brothers would end up central to the ceremony's only real controversy; and yet, thanks to Russell Brand's purity-tweaking jokes and Jordin Sparks's impassioned tirade against sluts, there they found themselves. Would the squeaky-clean trio retaliate by wagging their ringed fingers in Brand's face, or would they take Courtney Love's colorful advice to sample "some pussy and some cock and shut the hell up"? According to the BBC, they chose a different route, claiming to be fans of Brand (thanks to his last Conan O'Brien appearance) and giving him some pointers on pleasing the fickle American audience:

Look, we're old. Not "old" old, but more like "the Olympics were so much better in Los Angeles" old. And definitely not "Beatlemania" old, but old enough to wonder if the Jonas Brothers phenomenon is anything like what we've heard about Beatlemania. We honestly don't know — before today we'd never listened to a Jonas Brothers song, we've never seen them perform, we don't even know which is which, only that the moppiest-headed one occasionally receives photos of Miley Cyrus eating her skivvies. But this week's seismic release of the new Jonas Brothers album A Little Bit Longer — and the ensuing tear-streaked, hair-gnawing tween bedlam (best evinced by the accompanying snapshot from the group's recent TRL appearance) — has us taking the Jonases' impact much more seriously. After all, today's young pop heroes are tomorrow's clinically wasted reality TV icons; on that basis alone their soaring stars deserve a closer look and deeper understanding — or at least a handy Defamer fact sheet for your water-cooler convenience. Everything you need to know is after the jump.I. KNOW YOUR JONASES
