Nick Carter is mourning the loss of his baby girl.
The Backstreet Boys band member, 38, revealed his wife Lauren Kitt Carter suffered a miscarriage. “God give us peace during this time. I really was looking forward to meeting her after 3 months. I’m heartbroken,” Carter tweeted on Monday.
“It was a little sister for Odin,” the singer added.
The Carters, who wed in April 2014, are parents to 2-year-old son Odin Reign.
A rep for Carter did not immediately respond to PEOPLE’s request for comment.
The father of one, who is currently on a solo tour in South America and Mexico, nearly canceled his concert at Barranco Arena in Lima on Monday.
“I don’t think I can perform tonight. I’m sorry Lima,” Carter tweeted before posting a follow-up tweet that read: “This will be hard, but for the love of my fans here in Lima I’ll be on the stage tonight.”

During a pre-taped video package, he announced he was expecting his first child and detailed the year-long pregnancy journey that included going through a painful miscarriage.
“It’s been rocky, to be quite honest with you. There have been times when we thought it wouldn’t happen,” Carter told viewers about losing the baby before revealing that Lauren was 16 weeks along.
“It was really hard on Nick,” Lauren tearfully said in the footage. “Just watching him get so excited about something, and then see him so hurt. That was hard.”
