Kylie Jenner recently travelled to Paris with Guerrero

Guerrero, who worked with dozens of A-list celebrities, died suddenly and unexpectedly over the weekend.

The hairdresser began working with Jenner in 2019 and traveled with her to Paris last month.

His sister confirmed his death in a post to a GoFundMe fundraiser, writing: “My name is Gris, Jesus’s younger sister. It is with a heavy heart that we let the world know that Jesus Guerrero has gone to heaven. He is a son, a brother, an uncle, an artist, a friend, and so much more.

"Born and raised in Houston, TX, to immigrant parents, Jesus learned how to work hard and dreamt of taking his skills to the top.

“Unfortunately, his passing came very suddenly and unexpectedly. Currently, his family is taking care of his personal belongings and accommodations to bring him home to Houston.”

She concluded: "We hope that you find it in your heart to help in any way and/or share this GoFundMe."

In another post to his Instagram story, his family wrote: "Our family would like to thank everyone for all the love and support during this hard time. Jesus was the brightest light, we have never doubted that he touched the hearts and lives of everyone he came across.

"We have fallen into tears repeatedly reminiscing and wondering what we could have done different to still have him with us.

"Seeing everyone's loving posts, fills and tears our hearts all at once. If anyone has videos or photos they'd like to send us through here, we'd love every frame.

"I don't know how the world will go on without his light but I know he'll give us the strength to push past any obstacle. RIP Jesus, we all love you."

The cause of Guerrero's death is currently unconfirmed.
