Adele & Christina Aguilera Hang in L.A.
It was a collision of diva power, as Christina Aguilera and Adele spent time together backstage at Adele's show at The Greek Theatre in Los Angeles last night. "'Someone Like You' is my favorite! Beautiful to see all her fans sing it tonight! ;-) love u Adele," Christina tweeted along with two photos of the women. British singer-songwriter Talay Riley recently revealed that Christina has listed Adele's latest disc as an inspiration for her upcoming album. "She [Aguilera] wants this album to be the one which touches people and reflects all the personal experiences she's been through in the last few years," Riley told U.K.'s the Daily Star, adding the "Bionic" singer "sees Adele as her new inspiration."

Black Sabbath & Ozzy Osbourne Reunite For Album, Tour --Debunked! Tony Iommi has responded to the report, calling it "absolute nonsense." Read the Full Story
The original line-up of heavy metal overlords Black Sabbath is reuniting with plans to tour and release a new album. Though the original members -- guitarist Tony Iommi, bassist Geezer Butler, drummer Bill Ward, and, of course, Mr. Ozzy Osbourne on vocals -- reformed at Ozzfest '97 and played together through 2006, they haven't recorded together since 1979. The album will be Sabbath's first since their Ozzy-less effort in 1995. "We're all really looking foward to it and I think the stuff we've been writing is really good. It's more back to the old original stuff," Iommi said. (U.K.'s Birmingham Mail)

AC/DC Lauching Wine Line
Rock legends AC/DC have always seemed like the whiskey and beer type, but that's not stopping them from becoming the latest of many musical acts, such as the Rolling Stones and Madonna, to launch their own brand of wine. The band has teamed with Australian winery Warburn Estate to produce a collection of AC/DC wines based off their biggest hits, including: "Highway to Hell" Cabernet Sauvignon, "You Shook Me All Night Long" Mostcato, and "Hells Bells" Sauvignon Blanc. Drink up, rock on. (BBC)

Muppets 'Green Album' Now Streaming on NPR
"Muppets: The Green Album," which features Weezer, OK Go, My Morning Jacket and a slew of alt-rock favorites covering classic Muppets tunes, is now streaming in its entirety on NPR. Damian Kush of OK Go spoke with Billboard about his band's involvement in the album at Lollapalooza and teased a "twisted, kind of dark" variation on the "Muppet Show Theme." That opening track -- combined with moody covers from the Airborne Toxic Event, Amy Lee and Andrew Bird -- suggests that perhaps it isn't so easy being green. Listen over at NPR.
