Seacrest, 41, said that he was especially inspired after watching his younger sister, Meredith, marry her longtime love, Jimmy Leach, in Mexico last month.
"Did she inspire me to get married? Is that what you want to know?" Seacrest, who was his sister's man of honor, joked to ET's Katie Krause. "I really enjoyed it. I thought to myself, 'This is something everybody needs.'"
Seacrest also gave ET an update on two shows his production company, Ryan Seacrest Productions, produces -- Rob & Chyna and Keeping Up With the Kardashians.
"I don't know that we have announced [season two] yet, but we have had incredible success with the first season [of Rob & Chyna]," he explained. "I mean, we were all very excited to see how many people were tuned in and watching the show."
As for KUTWK, Seacrest confirmed that the series is currently in production, following a brief halt due to Kim Kardashian West's traumatic robbery in Paris, France.

"We have not stopped production," he dished. "We stopped for a little bit right after their incident in Paris, but we are shooting the show right now -- we're shooting season 13."
Luckily, according to Seacrest, the entire Kardashian-Jenner clan seems to be in better spirits now following both the robbery and Kanye West's recent hospitalization.
"Everyone's doing better," he explained.
As ET previously reported, the "Famous" rapper was transported to the UCLA Medical Center in Los Angeles after abruptly canceling the remaining U.S. dates of his Saint Pablo tour. He was released on Wednesday around 2 a.m. after spending nine days in the hospital for what one source claimed was "a mental breakdown."
