Caitlin Jenner is reportedly about to walk down the aisle for the fourth time.

Jenner, 68, is set to marry 21-year-old Trans woman Sophia Hutchins.

Hutchins is a student at Pepperdine University in Malibu.

She transitioned when she was a teenager.

The pair was first spotted in 2017 when they vacationed together in Mexico.

A source close to the couple reportedly said Jenner is "in a rush to wed for the fourth time".

Radar Online reports the couple plan to marry each other this summer on a bluff near Jenner's Malibu home.

The guest list is limited to a handful of close friends and family members.

The Kardashians are reportedly not on the guest list following estrangement after Jenner's tell-all memoir.

A source close to the pair has said of the pair "She and Sophia have a lot in common...

"The age difference doesn't seem to matter at all."
