"Let's Just Do It" is a posthumous single by the American rapper, singer, and songwriter Lisa "Left Eye" Lopes, and is the lead single from her first posthumous album, Eye Legacy.

The song was originally recorded in 1998 by Tionne and Lisa for possible inclusion in the 1999 multi-platinum FanMail. The song was not included with FanMail as it did not fit the album's sound, because the album focused on futuristic production.

When the idea for Eye Legacy was brought about, "Let's Just Do It" was selected to go on the album and was then chosen to be the lead single. In 2008, Missy and Rozonda recorded new vocals on the song, whilst the track was remixed and was given a new beat.

The track was first played November 5, 2008, at Hot Dance Airplay reporter WDRE/Nassau, New York.

The song samples "State of the World" by Janet Jackson without credit.

On June 2, 2014, a new version of the song was released on CD Baby and featured a new beat and rap from Reigndrop Lopes, who is a Hip rock artist and also Lopes' younger sister.

Despite the low download sales of the single, "Let's Just Do It" received a very positive review from Billboard magazine. It says "The energy that made the trio's upbeat singles international smashes is evident here, along with Lisa's essence—a reminder that TLC was among the most successful female R&B groups of all time. Originally recorded in 1998, the Heavy Weights and Marcus DL's production builds a catchy and contemporary rhythmic structure."

The track sold less than 1,000 downloads during the week of the single's release, according to Nielsen SoundScan. Because of this, the song failed to chart in the US Billboard charts and failed to be released worldwide.
