What is the new song (maybe feat lil wayne) on top 40 xm?

There is a new song on xm and it's got a slow sexy feel to the chorus. I think it may feature lil wayne. I know it's something about a girl. Eh it's not the motto. thanks though! I don't think it is super popular yet because I haven't heard it on the regular radio. I know it is on the top hits station but sometimes they play things that i've never heard before.
