Catalina Mancera, the pregnant girlfriend of late NFL star Marshawn Kneeland, shared ultrasound photos of their unborn baby in an emotional social media post. "My sweet baby, I dreamed of you long before I ever knew you," Mancera wrote via Instagram on Sunday, December 28. "I dreamed of building a family, of the life your dad and I talked about and imagined together. I'm so excited for you, but my heart still aches. It aches for the moments I won't get to share with him, and for the love I wish you could experience the way I did.
