Can anyone tell me the name of this Gwen Stefani song?

I can't exactly remember when it came out but its been within the past 5 years. I can't remember any of the lyrics but i just remember the video and I know I like the song. In the video, Gwen Stefani is dressed in a white dress (I think) and she's jumping around on a bed. It looked very similar to the video for '4 In The Morning' except in this video she's very happy, not sad. I can't remember anything else about it. Please, someone tell me what song it is!
