Welcome to Buzzworthy's "The Week In Pop," where we round up new album releases, talk show musical guests, and TV performances by your favorite pop stars and more (so you don't have to).

This week, No Doubt return with their first studio record in 11 years. They're on "The Ellen DeGeneres Show" on Tuesday and Wednesday. Green Day release ¡Uno!, the first album of a trilogy. They're scheduled for "Jimmy Kimmel Live!" on Tuesday and "The Ellen DeGeneres Show" on Thursday, though this may change as last night Green Day announced that Billie Joe Armstrong is seeking treatment for substance abuse. Meanwhile, Lupe Fiasco readies a Food & Liquor sequel (watch his stirring clip from "RapFix Live"; Thursday he's on "Late Show With David Letterman"). Also, T-Pain celebrates his birthday with a mixtape, plus deadmau5 and Mumford & Sons drop new albums. In movie land, Selena Gomez becomes the animated character Mavis and Cee Lo Green voices Murray in Hotel Transylvania, which hits theaters Friday.

NEW ALBUM RELEASES

+ No Doubt, Push And Shove: After 11 years between studio albums, the SoCal group fronted by Gwen Stefani release their fifth album. The 11-song set includes a collaboration with Major Lazer and reggae artist Busy Signal for the title track. The dancehall-tipped "Settle Down" video reenacts the band's reunion, which turns into a concert rager, and their just-released single, "Looking Hot," has a driving club rhythm percolating underneath guitar melodies on the dance-rock tune.

+ Green Day, ¡Uno!: It's the first of a three-album trilogy (which is also the subject of two documentaries) and comes off the heels of releasing a career-spanning box set. Billie Joe Armstrong told MTV.com that "There really is no theme to the first album, I think it's just more like a back to the basics, down and dirty rock 'n' roll record, power-pop," adding that influences on the album include Ramones, early Beatles, and Cheap Trick. Watch the steamy video for first single, "Oh Love."

+ Lupe Fiasco, Food & Liquor II: The Great American Rap Album, Pt. 1: The intelligent, socio-politically-minded rapper has made provocative rounds of late (from saying he won't vote to being a target of Twitter hate via Chief Keef, though Keef claims he was hacked), and Lupe's new album is no exception. He sparked an important B-word debate with "B---- Bad." "Around My Way (Freedom Ain't Free)" sampled Pete Rock and CL Smooth's "They Reminisce Over You (T.R.O.Y.),"which spurred a heated exchange. He also tackles 1800s-era women's inequality on "Lamborghini Angels."

Check out more new album releases and upcoming TV appearances and performances after the jump.

+ Mumford & Sons, Babel: The British folk-rock outfit have been roadtesting a few new songs while they've been touring, including "I Will Wait," "Lovers' Eyes," and "Ghosts We Knew." Gauging from those select songs (to appear on their 12-track sophomore effort), the band has continued to hone the four-part harmonies and storytelling style they crafted so well on their debut, Sigh No More. They also approached it with an added intensity, as they told Matt Pinfield on "The Hivecast."

+ T-Pain, Stoic: For his Sept. 30 birthday, T-Pain is giving fans the gift of music...in the form of this mixtape. Describing the set to Yahoo! Music, he said, "It's basically an outlet for me, and it's so many different genres of music on this mixtape, it's crazy." His first single is an ode to strippers (a subject not too foreign to him) "Don't You Quit," wherein he mixes lascivious objectification with references to Facebook, Instagram, and his awesomely coined phrase "going instaham."

+ deadmau5, > album title goes here <: As evidenced by a dedicated fanbase and his No. 6 spot on Forbes "World's Highest Paid DJs" list, Joel Zimmerman aka deadmau5 is one of the most in-demand EDM artist today. This 13-song set includes collabos with My Chemical Romance's Gerard Way ("Professional Griefers"), Cypress Hill ("Failbait") and Imogen Heap ("Telemiscommunications").
