"Lets Link" is a song by American rapper WhoHeem.

It was released on August 20, 2020, and garnered popularity soon after on the video-sharing app TikTok.

[2][3] On August 19, 2020, WhoHeem posted a video of him singing the song on his Instagram profile, asking his followers if he should release it next.

[5] By September 8, 2020, it was used in over 630,000 videos,[6] where it inspired the #SidePieceChallenge, which shows "sidepiece" girls exposing men for cheating on their girlfriends with them.

[7] Complimenting the "irresistibly catchy" hook and fingersnap heavy instrumental, Alphonse Pierre of Pitchfork said the song "seems inspired by San Bernardino, California rapper Whoheem's experiences hitting on girls in their Instagram DMs and it sounds as if it was written at his local mall's food court".
