Money might not be able to buy you class, but a stint on a third-rate reality show will buy you at least one radio single. 'Real Housewife' of Beverly Hills Lisa Vanderpump is the latest to parlay her Bravo "stardom" into a single. Follow the jump to listen!

Hmm.

Coldplay's Mylo Xyloto is having an extraordinary debut week, due in no small part to the album's included track "Princess of China" with Rihanna, which is burning its way up the iTunes Top Singles Chart. Not wanting to dust off the Rihanna-magic quite yet, Coldplay joined BBC's Radio 1 Live Lounge to cover the Barbadian Beauty's No. 1 single (and our current fave cardio motivational track), "We Found Love." Listen to the impressively executed cover, after the jump!

Enough unreleased Britney songs have leaked over the past 48 hours to make for a new EP! "Everyday," a rare ballad, whet our whistles for new Britney yesterday, with three upbeat new tracks following in the platform sneaker footsteps. With today's new songs, it's a bit easier to tell that the unreleased tracks are from previous album sessions (likely Breakout), but those details remain unclear. What is clear, however, is that for unreleased tracks, they're not so bad! Follow the jump to listen to "911," "Dangerous," and "Rockstar."

The unreleased Britney Spears track "Everyday" hasn't even been online 24 hours, yet the Internet is already hailing it as her "Beautiful" moment. Follow the jump to listen to the rare Britney ballad and let us know what you think!

The album version was the first slow-to-mid-tempo track we've had from Britney in a while, but don't expect the same from the single version that's been remixed for radio. The beat's been given a bump of Lohan powder, the vocals have been subjected to an extra dash of the Ke$ha tool in the editing suite and a few extra sound-effects seemingly culled straight from the Terra Nova premiere have been added, making for a slightly-different track. Follow the jump to check out the radio single version of Britney Spears' "Criminal."

Sure, it's really Luciana's club-thumping dance single "I'm Still Hot" (with Betty White), but when it comes to the legendary Betty, it's federal gay law to put her name first on EVERYTHING. Follow the jump to listen to the reworked club hit featuring new vocals by Betty White-hot!

With a title reminding us of our pop's advice for navigating urinals (not the way Larry Craig or other GOP closet-cases navigate urinals), "Shake It Out," the new track from Florence + The Machine, is instantly bright and beautiful. But who cares what we think! Follow the jump, take a first listen to the new Flo and let us know what YOU think, Instincters!

We gave two new David Guetta tracks (featuring two gaydored divas!) a spin this afternoon, and, in testament to Guetta's production abilities, we could not stop dancing! But it wasn't all partying at work in the name of research: imagine our chagrin when our Midtown Manhattan building started to shake as we danced. We've been upset that we've broken our liquid-only diet over the weekend to snack on an iceberg lettuce chip for nutrients, but we didn't think we'd gained thaaaat much weight. Anyway, East Coast earthquake humor aside, follow the jump to listen to two earth-shaking epic dance tracks from David Guetta's upcoming new studio album: "Turn Me On" (featuring Nicki Minaj) and "Night Of Your Life" (featuring Jennifer Hudson).
