What's the name of this music video and the artist?

I only remember some details from the music video. It's a black woman,
she looks good, I think she looks kinda like Leona Lewis. But in the
music video she is is sitting the whole time in front of a house or
club and she sings while she is sitting and it is evening. I think the
song is a bit techno/house but mostly just a pop song. And It might be
british I am not sure. That is all I remember. Please anything will
help just guess if you don't know. Thanks :)
