"Surprise!" she wrote, along with a series of shots showing off her baby bump. While fans were shocked, a source tells OK! that the singer was equally floored when she found out.
"Words can't describe the emotions that went through her," says the source, adding that there was a time that Halsey — who's been open about her desire for kids, as well as her past miscarriage and endometriosis diagnosis — wasn't sure that she'd be able to start a family.
"She sees this as a miracle," the source continues. "She literally can't stop cradling her bump."
According to the source, the 26-year-old is currently in her second trimester and feeling great. Alev, 37, "dotes on her, and she's following her doctor's advice by getting plenty of rest and just taking it easy," shares the source, adding that the songstress has kept her diet mostly healthy — but does give in to some cravings. "She likes cookies and gummy candy but tries not to go overboard."
As far as the baby's gender, "Halsey's hinted to her pals that she and Alev already know the sex. But they're keeping it to themselves for now," spills the source, adding that friends have no doubt that she and the filmmaker "would be thrilled" either way. "Halsey feels incredibly blessed."
As OK! previously revealed, Aydin is a screenwriter, producer and director who has worked on independent projects including the Netflix series Small Shots and Controller. The Turkish hunk has also been featured as an actor on the small screen in The Cat’s Meow, three episodes of General Hospital, Mother Hen, Lonely Boy and Cruel Hearts.
The low-key couple has been successful at keeping out of the spotlight, since they've only been photographed together once. Last October, the duo was seen at Blick's stocking up on art supplies in Los Angeles.
However last June, tattoo artist Amanda Owley shared that Halsey and Aydin got matching "SEEDS" tattoos on their feet at Liquid Tattoo in Yucca Valley, Calif. Owley posted a photo of herself with Halsey in a mask and another of the two together with their tattoos.
"Today I met the sweetest two people. Ashley and Alev. You may know her better as HALSEY," she wrote on Instagram. "@iamhalsey 'Seeds' is for planting seeds. She said this is cosmicly [sic] the best week to plant seeds in your life. I agree."
