Caitlyn Jenner is set to walk down the aisle — and based on her choice in a fiancée, she likes 'em young.

According to Radar Online, Jenner, 68, is set to marry trans woman and student Sophia Hutchins, 21.

Hutchins is currently a student at Pepperdine University and, like Jenner, transitioned into womanhood. However, unlike the conservative trans woman, she did so when she was a teenager.

Rumors of the two getting close began back in 2017 after they were spotted vacationing together in Mexico.

The site reports that the reality TV personality is "in a rush to wed for the fourth time" after the Kardashians gave her the cold shoulder following Khloé's scandal with cheating boyfriend Tristan Thompson.

"Caitlyn would have loved to have helped Khloé through the tough time in the delivery room, but the Kardashians have kicked her out of the family," an insider told the publication.

The couple reportedly plans to tie the knot this summer on a bluff near Jenner's Malibu home with a handful of their close friends and family members being present to witness their union. The Kardashians, however, are reportedly not on the guest list.

"She and Sophia have a lot in common," the source added. "The age difference doesn't seem to matter at all."
