"I am pregnant," Lowry wrote, revealing the she was "sad" that the news had leaked prior to her official announcement. "I'm sad that I should have known that people in my life would sell me out before I was ready. Like any normal person, I want it to be a happy time. I wanted this to be a private time so I could be excited while not getting chased by paparazzi and bothered with crazy headlines."
But the recent college grad is excited for her newest addition, adding, "Having another child is something I am so happy about and I just can’t wait. My boys are so excited, those who love me are so excited, and I hope that everyone can just be happy for me during this time."
