Arie Luyendyk Jr. & Lauren Burnham Have a Co-Bachelor & Bachelorette Party in Las Vegas

Bachelor couple Arie Luyendyk Jr. and Lauren Burnham cannot wait to tie the knot!

They got engaged on The Bachelor: After the Final Rose last March and are gearing up for their wedding in January.

The happy couple decided to celebrate their upcoming nuptials in Las Vegas and took a trip to Sin City over the weekend to have fun with some of their close friends.

According to Entertainment Tonight, the group arrived in Las Vegas on Thursday, November 15, and stayed at The Venetian Resort.

They were treated like VIPs the entire weekend and were even gifted a beautiful pink and gold cake from The Cake Boss’ Carlo’s Bakery.

Arie and his boys decided to have a fun night out at TAO on Friday, while Lauren and her friends had a nice dinner at Chica.

Their fun weekend getaway came just a few days after the happy couple announced they’re expecting their first child.

“I kind of had a feeling that I might be pregnant. So my friend insisted on bringing a pregnancy test over,” the 26-year-old recently told Us Weekly.

“Arie came out with the test in his hand and tears in his eyes. He was like, ‘You’re pregnant!’”

Arie immediately went to the store and bought more tests, which of course all came back as positive.

“Lauren took all of them and they were all positive,” Arie shared.

“We weren’t trying, but we are so excited. It’s going to be a whole new chapter in our lives.”

And, though Lauren has been having a rough couple of months, she’s starting to feel a lot better.

“October was miserable. I had really bad morning sickness and barely left the house. But over the last week I’ve started feeling a lot better, so it’s nice to have my energy back,” she said.

“When I wasn’t feeling that great, I was trying to go on a lot of walks. But now I do cycling a few times a week!”
