Chelsea Houska didn’t let Halloween festivities get in the way of updating on her pregnancy. The “Teen Mom 2” lead took to social media on Sunday to share a new bump photo with fans.

“Mama deer BUMP update!” Chelsea captioned a shot of herself in her Halloween getup. At “almost” 25 weeks pregnant, the 25-year-old said she’s noticing a lot of differences with her second pregnancy. “Bump is growing a lot faster and bigger than it did with Aubree,” she wrote.

While Chelsea did not share the gender of her and husband Cole DeBoer’s baby, fans speculated she could be having a boy. “Awwww it’s so little. I think it’s a boy! You look so beautiful!” wrote one Instagram user. “I think there’s a baby boy in there. So cute. You look amazing,” said another. “It looks like you’re having a boy. Your somtach looked like mine when I had my son 16 years ago,” added one fan.

Chelsea did not respond to the gender predictions, but she did make one thing clear: she’s not expecting multiples! After discovering that some fans commented “twins” on her bump photo, Chelsea offered a response on Twitter.

Chelsea revealed in August that she and Cole planned to publicly announce their child’s gender before his or her arrival in February. On Oct. 17, she apologized for the delay, saying they have been “crazy busy.” Previously, the MTV star said they were planning to do the gender reveal with a photoshoot or at a party. While Chelsea has been trying her best to keep the gender a secret, purposefully buying gender-neutral baby items, she’s made it no secret Aubree, whom she shares with ex-boyfriend Adam Lind, wants a sister.

Ahead of her latest bump update, Chelsea posted snaps from her family’s Halloween celebration, including pictures of her and her daughter’s matching costumes. “Ohhhhh deer,” Chelsea captioned a snap of Aubree, 7, sporting face makeup and antlers. A later post include a picture of mother and daughter at a trunk or treat party. Cole also got in on the fun by dressing up as an “old man.”
