Notable wedding guests included: Rumer Willis, Tony Dovolani, Sharna Burgess - all three were in the wedding party - Jenna Johnson, Nyle Di Marco and Candace Cameron Bure.
It was a weekend affair, with the whole group celebrating at the castle on Friday, the day before the wedding.
The 29-year-old actor and his 46-year-old love exchanged vows before 120 glittering guests during a nighttime ceremony at a Palm Springs hotel, according to PEOPLE.
The pair, who coordinated in white tuxedo jackets and black bow ties, were wed by none-other-than Kris Jenner, their longtime friend.
“If you can imagine Cher meets a Guns ‘N Roses video and that’s the theme of the wedding,” Leatham, who planned and designed much of the wedding himself, told PEOPLE.
