+ We've been on baby watch all week, and now Wiz Khalifa and Amber Rose have finally welcomed their first child, baby Sebastian Taylor Thomaz, into the world. "Happy Birthday Sebastian "The Bash" Taylor Thomaz!!!" tweeted the proud papa. (MTV News)

+ "Saturday Night Live" has welcomed many talented hosts and artists, but Justin Timberlake is definitely on our "Best Of" list -- "D*** in a Box" alone is a LOL classic. JT is returning to host and serve as "SNL" musical guest on March 9, just 10 days before he drops The 20/20 Experience. (MTV News)

+ If Beyoncé's new trailer for her "Mrs. Carter Show" World Tour is any indication of what to expect, she'll be working the stage like the Queen Bey royalty she is, natch. Watch the extended clip, which serves as a promo for her London O2 venue dates. (Flavorwire)

+ Rihanna's topless in the latest issue of V Magazine, adorned only by an equally sexy Kate Moss. Check out official photos from the spread (some of which leaked prior to release), and also watch behind-the-scenes footage from the shoot. (Idolator)

+ We might get to see much more of One Direction very soon. For their 3-D film, Niall Horan revealed that on a recent shoot they ventured into some usually private locales: "It's actually just been in the toilet with us, no lie. That is coming out Aug. 30, and it's going to be very all-access, all-areas." (MTV News)
