• Hilary Duff posted a new Instagram photo with her husband Matthew Koma
  • Fans took her caption as a hint she might be pregnant 
  • Koma commented on the post to address the baby speculation

Fans of Hilary Duff are convinced that her fourth child is on the way. Speculations grew rife after the actress shared an Instagram post seemingly hinting that she is pregnant.

On Monday, the “How I Met Your Father” star posted a photo of her and her husband Matthew Koma sitting on a plane wearing face masks. The photo shows Koma staring at Duff while the actress keeps her eyes closed.

“Leaving for a little bit… The 3 of us,” Duff captioned the post before adding a smiling emoji and tagging Third Eye Blind’s Stephan Jenkins, who is seen sitting a few rows behind them.

“The three of you? Are you pregnant?” one fan commented. “Whaaaat??? Is this your subtle way to announce you’re pregnant?? Girrrrl congrats!” another wrote.

Duff shares daughters Banks Violet, 3, and Mae James, 8 months, with Koma, and son Luca Cruz, 9, with ex-husband Mike Comrie. To address the baby no. 4 speculation, Koma commented on his wife’s post, writing, “She’s talking about @stephanjenkins sitting behind us you baby crazies.”

He also posted on his own Instagram page a photo of him kissing his wife on the cheek as she smiles with her eyes closed. “Just the three of us (Stephan’s version),” he captioned the post.

Back in September, Koma posted what he called his “favorite” photo of Duff holding Mae James, who was only 5 months old at the time.

“One of my favorite pictures of wifey somewhere between supremely fulfilled, exhausted, and why the f*** are you taking my photo,” he wrote. “She started her new show this week and it’s so rad watching her kick into that mode. It’s easy to forget when she’s nailing it as a mama bear, wife, family psychologist and chicken lady, that she was first an absolute ace at what she was born to do. A really f****ing cool magic trick. This show is gonna be epic,” he added.

In response, Duff joked that her husband’s tribute was “bound to get him baby number 4.” “Oh you’re gunna get it. This is bound to get him baby number 4 and subway night 3 tonight,” she wrote.
