Heidi Montag posted a baby bump photo at six months pregnant over the weekend.
"So happy to be home! #6monthspregnant," the first-time mom-to-be captioned a picture of herself and Pratt standing in front of a scenic backdrop.
Montag followed up by sharing a photo of herself with her mom, Darlene Egelhoff.
Her relationship with her mom has improved since she and Egelhoff appeared on "The Mother/Daughter Experiment: Celebrity Edition."
"Ok top of the world with my mama! #6monthspregnant #colorado #cb," the star wrote.Montag announced her pregnancy in April, and confirmed the next month that she's expecting a baby boy.
"It was in my heart to have a boy," she told Us Weekly at the time. "I thought Spencer really used to want a boy, and then a few months ago we had a conversation where he said, 'Let's just make sure it's healthy. Boy or girl, I don't care.'"
Montag came to fame on the MTV series "Laguna Beach" before starring with Pratt on "The Hills."
Her former co-star Lauren Conrad is also pregnant and expecting her first child with husband William Tell.
