Confirmed by Us Weekly, citing sources, Jenner will be one of the few celebrity guests present at the event.
A noted Republican and a Trump supporter, Jenner has expressed in the past on her reality series I Am Cait how she disliked Hillary Clinton and how she wants to use her status to help the LGBTQ community.
"Trump seems to be very much for women. He seems very much behind the LGBT community because of what happened in North Carolina with the bathroom issue," the 67-year-old said in June during an interview with STAT.
In April, Jenner had documented on social media her ability as a trans woman to use the women's restroom inside Trump Tower in light of the controversial North Carolina law which requires people to use the bathroom that corresponds with the sex stated on their birth certificate.
The move came after Trump had declared that transgender people should be able to use whichever bathroom they want.
