Looks like things are still rocky between Heidi Montag and her former co-stars from The Hills

A source close to the mother-to-be, who announced her first pregnancy with hubby Spencer Pratt back in April, exclusively tells Life & Style that even though the couple is more excited than ever to welcome a baby boy, their MTV castmates haven't been there for them.

“She thinks her former co-stars have shunned her because she feels like none of them have publicly supported her during her pregnancy,” an insider reveals.

According to the source, fellow expectant mother Lauren Conrad has kept her mouth shut regarding her former best friend's pregnancy, and Heidi “is crushed” by the way she’s being ignored.

And though Audrina Partridge and Kristin Cavallari wished her well after hearing the news, Heidi is hurt to have gotten no love on social media.

This isn’t the only drama Mrs. Pratt is dealing with. As Life & Style previously revealed, tensions have been high between the reality star duo as Spence isn't pulling his weight around the house.

“Heidi is thrilled about being pregnant, but Spencer is making the experience very difficult for her,” a source revealed. “He’s made it very clear that he will never, ever change a diaper. He’s been so unsupportive.”

But amid all the drama, the 30-year-old is staying positive, and recently took to Instagram to post an adorable sonogram pic of her baby boy, who she adorably dubbed “my angel.”

"It was in my heart to have a boy," the MTV alum told Us Weekly in May. "I hope to have a little girl one day, but for my first child, I really wanted a son.”

We hope the co-stars can mend their friendships!
