It’s been two months since Heidi Montag announced that she’s pregnant with baby No. 1, but as Life & Style reported, the 30-year-old “is crushed” over how little her former Hills co-stars seem to care.

Now, the mom-to-be is worried that none of them will show up to her upcoming baby shower. “All Heidi wants is to be seen as part of the group again,” a source explains. “She’ll be completely embarrassed if they don’t come.”

Even though Lauren Conrad and Whitney Port are also expecting their first children, the Celebrity Big Brother alum is disappointed that she hasn’t heard from the women, who used to be two of her best friends. Not to mention, Heidi’s hubby Spencer Pratt has been far from helpful throughout this entire process.

“Heidi is thrilled about being pregnant, but Spencer is making the experience very difficult for her,” an insider previously told Life & Style — including during a recent move to a new home in Rancho Palos Verdes, CA. “Heidi had to pack everything. Spencer didn’t lift a finger,” the insider shared. “When Heidi asked him for help, he told her she could handle it herself.”

Plus, the insider added, “He’s made it very clear that he will never, ever change a diaper. He’s been so unsupportive.”

Heidi revealed last month that the couple will welcome a son in October. “It was in my heart to have a boy. I hope to have a little girl one day, but for my first child, I really wanted a son. I’m hoping to God that we don’t just have one, but if we do, I wanted a son,” she told Us Weekly.

Here’s hoping The Hills gang will all reconcile and get together for playdates!
