+ Watch Selena Gomez and her fellow "Spring Breakers" stars Ashley Benson and Rachel Korine karaoke to Britney Spears' "...Baby One More Time." "Awww @selenagomez can duet with me anytime," Britney tweeted with a link to their clip. (E!)

+ Maybe Justin Timberlake's seven-year music break was a good thing, because now we get to see WAY more of him (talk about making up for lost time)! He's added "Target Presents the iHeartRadio Album Release Party With Justin Timberlake" TV special to his appearances. It airs on CW at 8 p.m. ET on March 19. (MTV News)

+ Watch Kelly Rowland's video for the flirty get-it-on jam "Kisses Down Low." The song appears on her forthcoming Talk A Good Game. (Rap-Up)

+ Snoop Dogg's metamorphosis into Snoop Lion comes full circle with the new song "No Guns Allowed," which he performed on "Conan." Backed by his daughter Cori B. and other young singers during the set, the former gangsta rapper's contemplative tune advocates peace. (Rap-Up)

+ Rihanna has cancelled a second date on her "Diamonds" tour." Following Sunday's Boston cancellation, last night's concert in Baltimore was nixed, too. She's reportedly suffering from the flu and laryngitis. Get well soon, RiRi! (MTV News)
