Looking for a new 2011 r&b song that I can't find?

I heard it on the radio a couple weeks ago but I never figured it out.
It is kind of like a hip hop/rb song and the only lyrics I remember
are "oh o-o-oh oh, eh e-e-eh eh" from the chorus, sorry I know this
is really vague. I think the chorus was sung by a woman. Thanks in
advance :)

Other songs with "eh" or "oh" in the chorus that I already know isn't
it:
1) Lady Gaga - Eh Eh (Nothing Else I Can Say)
2) Good Charlotte - Like It's Her Birthday
3) Shakira - Waka Waka (This Time for Africa)
