"I couldn’t believe it. Immediately I started shaking. I was trying to text everyone that I knew to let them know and I was speechless. I could not believe it. I was home, here. I just so happened to be watching TV and I saw this newsflash and I still can't believe it when I hear them paying tribute to her on the radio, it's still such a shock to me. I don't want to believe it."

Despite the fact that the two recently reunited over lunch, a source tells Life & Style mag, "They were being careful, you could tell. Kim gave Reggie a kiss goodbye on the cheek. It wasn't romantic. If Kim had any feelings that it was going to be romantic, she wouldn't have gone somewhere so public."
