Alev Aydin/Instagram Last month, the musician appeared on The Tonight Show where they revealed that Ender doesn't like their singing. During the interview, host Jimmy Fallon congratulated Halsey on becoming a mom since they last saw each other and asked if their baby boy loves when they sing lullabies. "Oh….no. No, he hates it. He's my biggest critic," the singer responded. "It's funny. My mom, she can't carry a tune in a bucket. It's really bad and when she sings, his eyes light up like she's the stars and the moon. But when I sing, he's not a fan." Halsey then teased that whenever they sing, Ender gives them a pouty face as if he's going to cry, adding, "And I'm like, ' Alright, most kids would be really happy.' " In May, Halsey posted a series of candid videos to their Instagram Story getting about the health issues they've been experiencing since giving birth to their first baby. Halsey/Instagram "Obviously my health has changed a lot since I got pregnant and gave birth. I started getting really, really, really sick," they continued, adding that they've been "kind of" sick for "most of [their] adult life, but it started getting really bad." "I was hospitalized for anaphylaxis a few times and had some other stuff going on. Basically, after seeing like 100,000 doctors, I got diagnosed with Ehlers-Danlos syndrome, Sjogren's syndrome, Mast Cell Activation Syndrome (MCAS), POTS (postural orthostatic tachycardia syndrome)," Halsey — who is wearing a heart monitor — said, noting that they're still looking for the "root cause of some of these things." Halsey went on to tell their followers not to worry and that they're on a treatment plan, adding that they're in rehearsals for tour and "really excited and really confident" they can do it in a way that's "healthy" and can perform their best for fans.
