Does anyone know what this R&B song is?

I don't know many of the words. But there is this woman singing the chorus that sounds a lot like Beyonce maybe; who keeps singing about how she is "living my life."

Then when it gets back from the chorus and back to the song, its a couple of guys slow rapping. The song ends with the girl and the two guys alternating "living my life."

It's fairly new. I'm not sure how new, but it's a modern R&B song. I wish I could give more, I didn't hear the whole song.
