'Dancing With the Stars' pro Lindsay Arnold is expecting a baby girl

The couple are expecting a baby girl.

"Dancing With the Stars" dance pro Lindsay Arnold is overjoyed that she and husband Samuel Cusick are expecting a baby girl.

Arnold, who was last partnered with former White House press secretary Sean Spicer on the reality dance competition, shared the good news on Thursday.

"IT'S A GIRL!!!!" she said in the social media post. "We could not feel more blessed or excited for our sweet little girl to come into this world!. We already love her so much."

In the photo, Arnold, 26, looks like she is in total shock while husband Cusick is beaming broadly as pink confetti rains down on them.

The two held a gender reveal party and filmed it so they could share their special moment with friends, fans and family. The video shows the adorable moment of Arnold jumping for joy and throwing herself at her husband once it fully hits her that they're having a baby girl.

The home video also includes sweet footage from their ultra romantic wedding and honeymoon.

Funny enough, while the two were parked outside the clinic, Arnold disclosed that they both seemed certain they were having a boy.

The entire "Dancing With The Stars" family showed up in droves on Thursday to congratulate the couple, with Emma Slater spamming the couple with heart eye emojis while writing "YESSSS!!! Aunty Emma is ready." Meanwhile, current Mirrorball champ Alan Bersten ecstatically gushed, "I can’t wait!!!!!!!!"

Arnold is due mid-November.
