Nick and Aaron Carter's sister Angel Conrad welcomes first child

The younger sister of Backstreet Boy Nick Carter and twin sister of singer Aaron Carter, Angel Conrad, is officially a mom!

The model and House of Carters alum took to Instagram earlier this week to announce that she and husband Corey Conrad have welcomed their first child together, a baby girl named Harper Noelle.

"January 4th, 2019 at 4:28AM our precious baby Harper Noelle Conrad entered this world," Angel wrote, captioning a sweet slideshow which featured the couple at the hospital with the Carter family's newest little addition. Alongside a heart emoji, she added, "We are so in love!" In a follow-up post, the new mom welcomed her newborn daughter to the family of three's Los Angeles home, writing, "Our beautiful baby girl! Still can't believe she's mine. Welcome home, baby!"

For his part, Corey, who's the vice president of the real estate company Strategic Alliances & Entertainment at Caruso, shared a number of the same photos, writing, "My world has changed forever! On January 4th, @angelcharissma and I welcomed Harper Noelle Conrad!" Alongside two heart emojis, he continued, "I'm the luckiest man in the world to have two healthy, beautiful girls! #mydaughter #harpernoelle #mygirls #cedarssinai #cedarsbabies."

According to Entertainment Tonight, Angel, 31, and Corey first announced they were expecting baby no. 1 in June 2018. "We're so excited to meet our little one this winter!" Angel wrote to her social media followers at the time, captioning a snapshot of the parents-to-be holding up balloons spelling out "baby." She added the hashtags, "#pregnancyannouncement #growingahuman #babyduejan2 #babyconrad."

The Carters aren't the only celebs to share an exciting baby announcement in 2019. As Nicki Swift previously reported, Girl Meets World star Danielle Fishel revealed that she and her husband, Drop the Mic executive producer Jensen Karp, are expecting their first child together, a baby boy.

"I'm eating for two," the 37-year-old actress, who married Karp in November 2018, wrote on social media at the time. "I'm napping with wild abandon. Baby shoes. Baby clothes. (I'm shopping). I'm nesting. I'm reading books. I'm madly in love with my husband. I cry at commercials. I'm a walking cliché. I've got baby apps. I'm confident. I feel inadequate. I'm showing one day and the next I'm not." Fishel continued, "I'm nervous. I'm excited. He's due in July. We can't wait. #BabyKarp2019."

Congratulations to Angel and Corey Conrad on their baby news!
