Lauren is pursuing a relationship with a man named Devin Antin two months after announcing her breakup from Ben, E! News reported.
An insider says Lauren and Devin were strictly friends before she filmed Season 20 of The Bachelor and their relationship has recently taken a romantic turn.
"They are dating exclusively," the insider told E! News of the new couple. "It happened fast."
When Lauren moved from her home with Ben in Denver, CO, back to Los Angeles, CA -- where her family and friends reside -- the aspiring model and former flight attendant reportedly began hanging out with Devin as friends until their dynamic grew into something more.
"They have been dating for a while now," a source told Us Weekly of Lauren and Devin, adding that the blonde beauty has already met members of her new beau's family. "She was at a Golden State game with his sisters."
Lauren and Ben called off their year-long engagement in May and have seemingly been on friendly terms ever since. Shortly after the split, Lauren talked to Us about the idea of finding love again.
"I'm not looking to force anything... I'm going to take it day by day. If something happens, great. If not, then that is how it's supposed to be. I'm just trying to focus on myself and my blog, focus on my projects and friendships and family. If something comes from that, great. I'll be so happy," Lauren explained.
"[But] even if something does come, I really want to take things slow. Because obviously on The Bachelor, things don't move slow."
In May, Ben told Ryan Seacrest on his On Air with Ryan Seacrest syndicated radio show that he wasn't ready to even think about dating again, and he assumed Lauren wasn't in that place yet either.
Ben and Lauren got engaged on The Bachelor during the show's March 2016 finale.
Six months later, the pair decided to star on their own The Bachelorspinoff on Freeform, Ben & Lauren: Happily Ever After?, which premiered in October of last year.

Lauren recently admitted to People she "didn't really want to do" the show and filming the series was a "high-stress situation" that definitely contributed to their breakup. She said her communication with Ben broke down during the show and she felt "very alone" because she wasn't receiving the support she needed.
For months prior to the official end of Lauren and Ben's romance, the pair was plagued with rumors their relationship was on the rocks.
Lauren also had to deal with the fact Ben called off their televised wedding due to cold feet. While Lauren was shown picking out bridesmaids dresses on Happily Ever After?, Ben was shown venting to friends about how he feared they were rushing into things.
"I think it was just a very abnormal situation and one that [was] unfortunate," Lauren told People, referencing the rise and fall of her relationship with Ben thanks to The Bachelor experience as a whole.
"I mean, we tried. We went to couples counseling. We continued that after the show and I went to personal counseling. I feel like we gave it everything we could, just at the end of the day, it didn't feel right anymore."
