"L8 CMMR", or "latecomer", is a song by British recording artist Lily Allen from her third studio album, Sheezus (2014).

It premiered online on 6 February 2014,[1] the same day as the release of her previous single "Air Balloon" music video.

This track follows the style of her previous single, "Air Balloon", and is a bubblegum pop and electropop song.

[2] The song also features heavy amounts of autotune, as well as chipper synths.

Spin gave a positive review of the song, calling it a "bright, bouncy electro-pop with well-crafted hooks and some playful Auto-Tune effects", but also stated it was a "little lackluster".
