+ Watch Katy Perry whip out the synth-tipped "Walking On Air" during "Saturday Night Live," a performance that boasted '90s-inspired choreography, some dramatic sheer pieces of cloth, and blowing fan action. (Can someone PLEASE follow us around with fans, too? Her hair looked stellar.) Katy also performed "Roar." (MTV News)

+ Check out a promo for Justin Bieber's forthcoming "Believe 3D" concert film. The clip shows how much Justin has grown up (#stache) and even includes a cameo from his mentor, Usher. The flick hits theaters on Christmas Day. (Billboard)

+ Adam Lambert will take on Lady Gaga's "Marry The Night" on the Nov. 7 episode of "Glee." See the promo, which reveals that night's show theme: "The Katy Perrys vs. The Lady Gagas." So, um... everybody wins! (Just Jared)

+ Taylor Swift spent Saturday in Nashville for the grand opening of the Taylor Swift Education Center. The "Red" singer donated $4 million to endow the center, which is located at the Country Music Hall Of Fame And Museum. (Just Jared)

+ Listen to a new Timbaland track featuring Jay Z and Drake. Timbaland previewed the still untitled song during the Birmingham, England, stop on Jay's "Magna Carter World Tour" last week. (Pitchfork)

+ Speaking of Timbaland and Jay Z, the pair were spotted (along with pal Chris Martin of Coldplay) taking the Tube to the "Magna Carter World Tour" concert at the O2 Arena on Saturday. (Just Jared)

+ Congratulations to Pharrell Williams and model/ designer Helen Lasichanh, who were married on Saturday in Miami. Busta Rhymes and Usher reportedly performed a mini-concert during the reception, but our invitation must've been lost in the mail so we can't confirm firsthand. (Billboard)
