The makeup mogul and model shared two posts of herself posing in a strapless Dior bikini on Monday, asking in the second post, “But are you registered to vote? click the link in my bio.. let’s make a plan to vote together.”

The US Presidential election is on November 3 and US states have differing requirements for voter registration.

A link in Jenner’s Instagram bio directed her 196 million fans to vote.org – a US voter registration site that allows US citizens to check their voter status in “30 seconds”.

Jenner also posted a series of Instagram stories about voter registration on Monday.
