Rihanna goes to Africa with Chris Brown, Lil Wayne speaks dinosaur, and more in 10 Things To Know Now!

1.) We're not sure if Rihanna and Chris Brown are officially back together (getting to the bottom of this AND the whole Justin Bieber/Selena Gomez situation is one of our 2013 New Year's resolutions), but the pair did recently vacation in Africa, and they looked like a pretty cozy couple. (RapFix)

2.) Lil Wayne will voice a character in Pixar's forthcoming animated film "The Good Dinosaur." No word on whether the animated dino will also rock a stellar ice grill. (PopCrush)

3.) Lady Gaga's next leg of her "Born This Way" tour will offer free mental health services for her Monsters via the "BornBrave Bus" with access to professional mental health services before her concerts begin. Dr. GAGALOO is in! (L.A. Times)

4.) GLAMBERTS, Adam Lambert is a film critic! Well, kinda. The "Trespassing" singer took to Twitter to complain about how "Les Miserables" cast all actors and no professional singers. And it sounds like one of the film's stars, Russell Crowe, agrees with Adam's critique! (MTV News)

Check out the rest of this week's 10 Things To Know Now after the jump!

5.) Saying goodbye to Christina Aguilera and Cee Lo Green as judges on "The Voice" for Season 4 was super SADZ, but catching these snapshots of hunky Usher and GORG Shakira as the new judge replacements makes us feel a little better. (That Grape Juice)

6.) Jay-Z will lend his talents to the forthcoming "The Great Gatsby" movie soundtrack along with The Bullitts, Prince, and Lady Gaga. Shhhh! If you listen closely, you can already hear the sound of EPICNESS. (Billboard)

7.) Don't take Azealia Banks' quitting-the-rap-game threats too seriously quite yet -- especially since she just dropped a new track called "BBD." She promises the track will be on her (very patiently awaited for) debut album, Broke With Expensive Taste. (Idolator)

8.) Check out MTV's list of pop albums we're very excited to hear in 2013, which includes Lady Gaga, Justin Bieber, Selena Gomez, The Wanted, Beyoncé, Katy Perry, and more. (MTV News)

9.) Brandy is totally sitting on "Top Of The World" after getting engaged over the holiday! SPOILER ALERT: Her ring is GIGANTIC. (RapFix)

10.) Dave Grohl may be taking a hiatus from the Foo Fighters, but he's already started a new band, Sound City. The group will perform at the Sundance Film Festival. (Spin)
