"U and Dat" is the second single from E-40's album My Ghetto Report Card. The song features T-Pain and Kandi Burruss, and it was produced by Lil Jon. A remix was released in early August with Juelz Santana, Snoop Dogg, and Lil' Flip. It was featured on an Amp'd mobile commercial. The track is credited to have popularized the use of T-Pain as a hook singer on hip hop tracks.
The music video is in a club scene and in a car. Most of the video includes T-Pain and E-40 scouting various women, Kandi Burruss and Ashalee Albar being just to name a few. Kandi's part in the video is to push off promiscuous men around her.
Lil Jon and Katt Williams make a cameo appearance in the video.
The song achieved a good amount of success. It reached a high of #13 on the Billboard Hot 100, making it both E-40's and Kandi Girl's highest-charting single to date.
