Bushnell, who has stayed mum about her new guy until now, posted a telling quote before finally sharing a pic of Antin looking back at her as they held hands. "You can't always wait for the perfect time. Sometimes, you have to dare to do it because life is too short to wonder what could have been," the quote read.
A source confirmed to ET last month that Bushnell was dating Antin just two months after her split from fiance Ben Higgins.
"It happened very quickly after her split with Ben, but [Ben and Lauren's] relationship was over way before it officially ended," the source said, noting that Higgins and Bushnell are still on good terms. "She is really happy with Devin and they're having a great time together."
Bushnell's pal, Amanda Stanton, meanwhile, told ET that Bushnell is really "happy." See more in the video below.
