"I'm pretty used to her doing that sort of thing," Brody says.
"It was a big disappointment," Brody told People about Caitlyn's absence. "Especially considering that she had known about the wedding for a year."
Cailtyn was reportedly set to attend the nuptials all along but had to bail last minute due to work commitments.
Brody said he "wasn't surprised."
"I'm pretty used to her doing that sort of thing," he said.
"We sent them an invite, but we never heard back," he said. "I would have loved to have had them there."
According to People, Caitlyn plans to throw Brody and his new wife a post-wedding party in Los Angeles sometime this summer.
