We gave you fair warning, but here it is. Rihanna, celebrating her 24th birthday today, released the remix to Talk That Talk's "Birthday Cake" featuring ex/current/who knows boyfriend Chris Brown (who tweeted "Happy Birthday Robyn" earlier today). But as followers of Brown's Twitter already know, RiRi also showed up on the remix to Brown's "Turn Up the Music," which dropped earlier tonight and ends with Rihanna laughing. "Let them be mad!!!!," tweeted Brown. "We make music. Don't like it, don't listen! Turn up the music remix is coming soon too! Guess who's on it?" And now we know.

We're guessing you may have a comment or two to say about these tracks, eh? Especially Brown's first line on "Birthday Cake": "Girl, I wanna f**k you right now/Been a long time, I've been missing your body." If you were worried about not having any post-Presidents Day water cooler talk, you're off the hook. Discuss.
