in desperate need of a H&M song (pronto.)

i love this forum!

can you help me with a song sung by a woman i heard in southern california...the only part I remember is "I will be okay" in the chorus (its repeated in the song so it's stuck, unlike the rest of the song), and the rest of the chorus has word rhyming with "okay" like "away"... at one point in the chorus theres a "dont you"..blah blah. there's a short rap part in the middle as well. the song feels hip-hop like but it's not completely, the beat and tune are catchy as well..

if it's any help, i heard the song "hot or cold" by katy perry shortly after/before this song..help?! please!

I think it might be Lady GaGa "Just Dance"
