Mark Ballas and BC Jean's vulnerable admission comes after they revealed in June that they're expecting

Mark Ballas and wife BC Jean are sharing a vulnerable song about a hard period in their lives.

On Friday, the couple released a music video to their band, Alexander Jean's social media platforms, sharing their latest single "Rainbow," which reflects on a pregnancy loss the couple experienced last year.

"We lost a baby last year," the caption reads. "Just when we thought we were in a good place to tell friends + family we received the heavy news that our little one wasn’t going to make it, we’ve both been through hard things in our lives but this was a different kind of sadness."

The caption concludes, "This song is for anyone that has experienced loss in any form, We hope it brings whoever listens some kind of peace & reminds you that a rainbow isn’t far behind."

The lyric video that goes along with the song shows Jean, 36, singing in an oversized coat while showing off her bump. The recently retired Dancing with the Stars pro, 37, who moved on from the series earlier this year, plays guitar.

The spouses shared the news of their rainbow baby on Instagram in June.

"Life Lately ☀️," they captioned a Reel, which showed recent adventures from beach days to a Disneyland trip, ending with their biggest project to date.

"Lately we've been...making new music, making birthday wishes, went to Disneyland, made more music stuff, turned off our phones and went to the beach, car rides with our best mate, Boba tea, made more music," the Reel read.

"Also," it continued, "we've been making.... a tiny human."

The couple first met "at a singer-songwriter night at a mutual friend's house," Jean told Riff Magazine. "It was kind of like a fun party night where singers and musicians would get up and perform."

After the event, the two exchanged numbers and eventually started dating in 2012. The couple later announced their engagement in January 2016 and tied the knot that November.

Earlier this week, the couple celebrated "baby's first concert," sharing scenes from a night out seeing Coldplay on Instagram.

"It was a beautiful night, we sang, danced, randomly ran into friends & had a lovely time, baby was busy kicking the whole show & even got a new T shirt 🥹," Ballas wrote in the caption.
