Halsey gave fans a glimpse into her new life as a mom by posting a breastfeeding selfie on August 23.
The snap showed the singer, 26, cradling her 1-month-old son Ender, who was dressed in a leopard print onesie.
"Welcome to the jungle 🐆," she captioned the photo, which also revealed that she was in a studio working on her makeup line About Face.
The "Without Me" crooner seemed to getting ready for a photoshoot, as she was rocking dark lipstick and had her hair pulled back in clips. There's also some camera equipment that can be seen in the background.
The singer welcomed her first child with boyfriend Alev Aydin on July 14, debuting their bundle of joy on Instagram five days later.
"Gratitude. For the most 'rare' and euphoric birth," she captioned the intimate set of photos. "Powered by love."
The New Jersey native has continued to update fans on her parenthood journey, sharing photos of her stretch marks and Ender's colorful nursery on social media.
Before giving birth this summer, the star experienced a miscarriage.
"I've been really open about my struggles with reproductive health, about wanting to freeze my eggs and having endometriosis and things like that," she previously shared. "For a long time, I didn't think that having a family was something I was going to be able to do, and it's very, very important to me."
"Then one day my OB-GYN tells me it's looking like I maybe can, and I was so moved. It felt like this ascension into a different kind of womanhood. All of a sudden, everything is different," she explained. "I'm not going to go tour myself to death because I have nothing else to do and I'm overcompensating for not being able to have this other thing that I really want. Now, I have a choice. I've never had a choice before."
On August 27, the singer's fourth album, If I Can't Have Love, I Want Power, will drop alongside an hourlong movie that will have a limited run in IMAX theaters.
Halsey described the work as "a concept album about the joys and horrors of pregnancy and childbirth."
