'Bachelor' Alum Arie Luyendyk Jr. Shares How Living With Lauren 'Strengthened' Their Relationship (Exclusive)

The 36-year-old reality star says he and his new fiance are doing "great."

Arie Luyendyk Jr. has only been living with fiancé Lauren Burnham for about two weeks, but it seems to be going well so far!

ET caught up with the Bachelor alum at IndyCar’s Toyota Grand Prix of Long Beach on Saturday, where he placed third in the Stadium Super Truck Series. Lauren was also at the event.

Arie dished about what life's been like since Lauren, 25, moved to Arizona to live with him. "It's been really fun," he shared.

"Her dog Dallas is so cute, and he gets along with my dog," he continued. "We're looking at houses, and it's a really exciting time of life so for me, it’s been really cool."

The 36-year-old race car driver added that he and Lauren really "get along" well, and that living together has been a positive experience thus far.

"I think it’s strengthened our relationship," he noted. "We love hanging out together, and we're very similar. We get along, and it’s just great."

Arie, who first proposed to Becca Kufrin during Season 22 of The Bachelor and then changed his mind and got engaged to initial runner-up Lauren in March,  also talked wedding planning, which he says is "going great."

The reality star further confessed that he and his bride to be are still torn as to whether they should televise the wedding versus have a private ceremony. "We're trying to see if we still wanna do the TV side of things or if we want to do it privately," he confided.

Regardless of the direction the couple decides to go, they have a lot of help with the planning -- and it sounds like they might need it, seeing as Arie revealed it "could be a big wedding."

"Our parents are helping, too," he disclosed. "Lauren's mom is being a big help, and the planning's going good. We always say we want a small wedding but then we keep looking at the guest list, and it keeps growing more and more everyday, so it could be a big wedding."

Arie added that the couple did recently meet with Marriage Boot Camp counselors Dr. Ish and Dr. V from the hit WE tv series in the hopes of getting some tips on how to make their marriage work in the spotlight.

"We went to lunch with them just to hear about their show, and they gave us a lot of good advice," he recalled. "It's always good to get advice. We've also met with Lauren's pastor at her church. So it’s good to really lean on people that you know can shed some light on how to help your relationship."

The auto racer, who has driven around both Kim Kardashian West and Bachelor host Chris Harrison, took his fiancé for a spin on the track over the weekend to give her the "full experience."

"Racing is something I've done my whole life," he said. "The Stadium Super Truck series is insane. Actually, Lauren got to take a ride yesterday during qualifying, and that was really exciting to have her experience that, so now she's definitely got the full experience."
