"That's That" (explicitly titled "That's That Shit") is the second single by Snoop Dogg from the album Tha Blue Carpet Treatment. The song was the first single taken from the album in the United Kingdom, however the single only achieved notable success in the U.S., where it reached #20 on the Billboard Hot 100 chart. The song samples the melody played in the 1988 film Coming to America during the bathroom scene when Eddie Murphy gets washed by female servants.

Snoop Dogg spoke to AllHipHop.com about the track off Tha Blue Carpet Treatment which Dr. Dre produced and features R. Kelly. Snoop explained "Dr. Dre called me today. We’ve been working on my record. He helped me fix this song I did with R. Kelly. It was a hit record before I gave it Dre, but now it’s a super hit record. He made me strike all my vocals. That means, 'Take all your lyrics off, I don’t like ‘em. They’re wack.' I even go through that shit too. To this day, you know what I mean? I ain’t too big to take criticism. He made me take all my lyrics off and me and D.O.C. had to come up with some more shit that was just extraordinary." The title comes from R. Kelly repeatedly saying "That's that shit!" in the song.

The song was performed live at the MTV Europe Music Awards 2006, although R. Kelly wasn't present. The curiosity of the live act was that the intro of the song was the same cut as in the movie with the Victoria Dillard skit at the end, which was left unedited in the direct broadcast, though in the later reruns of the program, "penis" was censored. Though R. Kelly wasn't present here either, the song was also performed live at the 2006 BET Hip Hop Awards and at the 2006 American Music Awards. R. Kelly's part was playback in the events.

The song samples a skit from the Coming to America score, which Dr. Dre helped to mix into a single. However he worked on the original movie as well, as he provided the track "Comin' Correct" by J.J. Fad for the soundtrack. He was credited the producer.
