Heidi Montag is "so excited" to celebrate Mother's Day for the first time as a mom-to-be.
The 30-year-old is expecting her first child, a baby boy, with husband and fellow ex-co-star Spencer Pratt. Montag posted on her Instagram page Sunday a photo of her showcasing her baby bump while standing amid a backdrop of a bridge over a river, taken last week.
