Double the fun!

The Hills alum Doug Reinhardt revealed on Saturday that he and girlfriend Mia Irons are expecting identical twin boys.

The couple made their big announcement at an intimate reveal party for their family and friends, which was hosted by Reinhardt’s mother, Kelly Roberts, and his sister Casey Beau Brown — who starred in Laguna Beach — in Newport Beach, California.

In one sweet video from the celebrations, Reinhardt, 33, and his girlfriend prepared to pop two large balloons — one of which was blue, while the other was pink — as their loved ones counted down to the big reveal. Then, as the couple popped their balloons, a wave of blue confetti burst out, prompting cheers all around.

Cleary overfilled with joy, Reinhardt could be seen jumping and throwing his arms up in the air with a big smile on his face.

“To the boys and @mia.keana#twins,” the former reality star captioned the clip.

In another sweet snap shared by Reinhardt’s sister, the pair can be seen giving each other a big kiss following the exciting news.

Alongside her own video from the big reveal, Irons shared that the couple first found out that they were pregnant at Christmas — a few weeks after her son from a previous relationship told Santa that his wish was to have a brother.

“Blessed beyond measure w/ the magic of IDENTICAL TWINS, due this Summer! Something so rare that I can’t even believe we’re this lucky to hit the odds of 0.3%?!” she wrote.

“This pregnancy was our 2018 Christmas surprise, ironically finding out just a few weeks after Koby met Santa & wished for nothing BUT a Brother. Today we waited to find out exactly who was coming into our life! Thank you @caseybeaubrown for throwing us an amazing party, you’re incredible!” she added.

In another sweet moment recorded by Reinhardt’s sister, Irons can be seen getting a big hug from her son as soon as he found out that his Christmas wish was coming true.

We’ve created such an amazing family life together, thank you forever! We got 2 IDENTICAL BOYS coming! BOYS! Wow my heart is so full! I can’t wait! I love you all! Thank you for coming & celebrating w/ us!”

Following the couple’s big reveal, a banner flew through the sky on an airplane. “Congratulations Doug & Mia on your twin boys,” it read.

The pair have been dating since last year.

Reinhardt — who has dated Paris Hilton, Amanda Bynes and Lauren Conrad —was previously married to Natalie Sutton. The pair tied the knot in October 2017, before splitting in 2018.

The former baseball player appeared on The Hills from 2008 to 2009.
