Lindsay Arnold, a DWTS pro, would like to welcome a new member to her family ...

Lindsay Arnolds, a professional dancer from Dancing With the Stars, has just grown by one.

Arnold's sister, Brynley Arnold, gave birth to a baby girl on Thursday, August 4, 2022.

Brynley wrote on her Instagram post that she is so grateful and blessed that she is here.

Lindsay Is So Proud of Brynley

Brynley Arnold McGinnis (@brynleyarnold) has shared a post.

Lindsay posted on her Instagram Stories that she was so proud of her little sister.

Lindsay wrote a letter to baby girl. I'm so glad you're okay.

Lindsay said she would start some dance lessons before heading out to meet the baby girl.

Im about to start my final class of the day!!!! she wrote. Im dying to meet baby girl!!! I'm so proud of you @brynleyarnold, I love you.

Lindsay then uploaded a video of herself driving to the hospital to see the baby.

The Dancing With the Stars family gave Brynley a lot of support.

Omg!!!! The baby girl is here! Congratulations to you two! professional dancer Emma Slater commented.

Daniella Karagach has also written, expressed her gratitude, and commented on her work.

Jenna Johnson, Krystyn Burtt, Elena Samodanova, Jordan Fisher, Ezra Sosa, and Shirley Ballas congratulated the family.

Lindsay Welcomed a Nephew Earlier This Year

Lindsay Arnold Cusick (@lindsarnold) has shared a post.

Jensen Arnold gave birth to a baby boy, Brooks Joshua, who grew up with the Arnold family by one in June 2022.

Brooks Joshua Hill. 6 lbs. 19 inches. Hes here, we are both healthy and so happy, according to Jensen on Instagram.

Arnold was said to be announcing a pregnancy with a new photoshoot, although it appears that this is not her intention.

Arnold posted a video with a text indicating Cusick Family 2020 VS 2022, but because the videos began with maternity photographs from 2020, some fans assumed Arnold was announcing another pregnancy before seeing the rest of the video.

Arnold flashes between photos of herself and her husband, Sam Cusick, and updated photos of the couple and their daughter, Sage.

Arnold's posting served as a vehicle to examine the difference between 2022 and two years earlier.

She wrote in her post that she can't believe she got to refer to these two as my own. I just love our little family! I'll cherish these two forever.

The hashtags and the photos as a whole were a bit confusing to fans.

One person expressed my belief that this would be a pregnancy announcement.

Another wrote, When you went on a girls trip with the dwts pros and u guys had your pink jackets you were sideways and I saw your belly and then u made a face like whoops and covered your belly quick. I was like awwww shes pregnant.

Arnold has not announced a pregnancy, however, and she has posted plenty of full-body photos and videos in the past weeks, including videos showing her entire midsection, which one fan refers to as flat and ripped in the comment section.

Season 31 of Dancing With the Stars will premiere on Disney+ on Monday, September 19, 2022. Derek Hough, Len Goodman, Bruno Tonioli, and Carrie Ann Inaba will return along with Tyra Banks and new co-host Alfonso Ribeiro.
