Ups sorry the news where old :p
the "single" was supposed to be released on April 4. What song she released? I didn't hear a thing about her that day :/
Here is the link: 
I have to defend RiRi for a sec! She is ungrateful but she's still humble. She has talent but not as much as Adele, obviously. Her weed pics and releasing albums constantly makes her look like an attention wh**e but at the end of the day is working for her so good for her. My problem with Rihanna is that she tries desperately to look hood but she ends up looking like a ratchet rat. In other news Queen B is releasing her single tomorrow :D
IMO I feel that Adele handles her fame naturally. She does music because she likes it and nothing more. Adele is a very humble person and so down to earth, also the main reason why I love her :)
She said in an interview in 2012 (I think, not sure actually) that she will take about a year to two years making her next album.
Adele HAS to be in Bey's new album, everybody would love it but judging by how is going the promotion of Beyoncé I doubt it :p
I would love it!!! Specially Queen B and Adele
