Looks like soon-to-be parents Heidi Montag and Spencer Pratt are hitting a roadblock in their relationship, and it’s all because of Spencer’s nasty attitude.

A source close to the couple exclusively tells Life & Style that, while this should be the best time of the expectant parents’ lives, The Hills alums are butting heads.

The parents-to-be, who will welcome a boy in October, bought a new home in Rancho Palos Verdes, CA, and Spence made his pregnant wife do all the heavy lifting!

“Heidi had to pack everything. Spencer didn’t lift a finger,” the source reveals. “When Heidi asked him for help, he told her she could handle it herself.”

To make matters worse, the 33-year-old dad-to-be has made it clear to his wife that he will not be taking part in the messy parts of parenting.

Even amid the relationship drama, Heidi is over-the-moon about her impending delivery and can’t wait to welcome a little boy!

"It was in my heart to have a boy," she said to Us Weekly. "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. I thought it’d be a more natural bond for Spencer since he and his dad are so close."

Well, we hope Heidi’s excitement balances out Spencer’s bad attitude!
