The last time Rihanna visited Japan was in February 2010, when she did a few photoshoots for Elle Girl Japan, Nylon and Exile.

RiRi has performed at the Grammy Awards last year, when she was joined by Eminem on Love The Way You Lie Part II and Drake on What’s My Name?.

In 2008, she was joined by The Time on a performance of Umbrella and Don’t Stop The Music.

She was supposed to perform Disturbia and Live Your Life with T.I. at the 2009 show, however, she was unable to attend due to the incident with her ex-boyfriend.

Rihanna also performed We Found Love at the latest Grammy Nominations Concert and Rehab  & Disturbia at the 2009 Pre-Grammy Party.

All videos are available after the jump, including a rehearsal video from 2009.

Drake and Rihanna have shot a music video for their latest collaboration, “Take Care”, from Drake’s latest album.

Director Yoann Lemoine tweeted:

Oh by the way I just shot Drake & Rihanna’s ‘Take Care’ video. Beautiful track, amazing artists. EDITING NOW ! http://bit.ly/zCZhAs
Almost looks like @drake is photobombing my picture with @rihanna Love you guys. http://twitpic.com/8hxkl6

Yoann has directed Katy Perry’s “Teenage Dream” and Lana Del Rey’s “Born To Die” videos.

“Take Care” is the duo’s first collab since Rihanna’s No. 1 hit “What’s My Name?”. Listen below:

• It has only been announced that Rihanna will perform “Princess Of China” with Coldplay at the Grammys this weekend. However, Rihanna’s dancers are rehearsing as well. Maybe we should expect a few surprises… The 54th Annual Grammy Awards will be held on February 12, 2012, at the Staples Center in Los Angeles being broadcast on CBS 8:00 p.m. ET.

• Would you like “Birthday Cake” to be a single? That’s what Rihanna asked her 13 million Twitter followers yesterday. She also tweeted: “Now here’s the trick question! #IF I put collaborator on it, who would u wanna see lick the icing off????? #CAKE I need somebody #DIRRRTY on my Birthday #CAKE ;) lol And please!!!! No girls allowed on #CAKE” Thoughts??

• Rihanna is this year’s 9th most desirable woman according to AskMen.com. “In her memoir Bossypants, Tina Fey cheered Beyonce for “bringing back the leg meat.” Well, Rihanna has taken that “leg meat” torch and run with it. Watching her dance makes us forget that we ever desired supermodels with sticks for legs. Even the snooty Brits can’t get enough of her. When Coldplay’s Chris Martin needed a female vocalist for his recent “Princess of China,” he got Rihanna — even though his wife Gwyneth Paltrow is trying to jumpstart her singing career. Sorry, Gwyneth, you’ve got no “leg meat.”"

Thanks to “You Da One“, the second single off of Rihanna’s “Talk That Talk” album, RiRi is now the third artist with most No. 1 singles on Billboard’s Dance/Club Play Songs — behind Madonna (40) and Janet Jackson (19) only.

“You Da One” has peaked at #14 on the Billboard Hot 100.

Rihanna’s former 10-week Hot 100 leader “We Found Love,” featuring Calvin Harris, dips 2-3 although it spends an 11th frame at No. 1 on Radio Songs (145 million, down 3%). “We Found Love” becomes the longest-leading song on Radio Songs since Alicia Keys’ “No One” reigned for 14 weeks in 2007-08 and is one of just 10 tracks by solo women to rack as many as 11 weeks at the summit in the all-format airplay chart’s 21-year history.

Congratulations, RiRi!!!
