K'rrik, Son of Yawgmoth and Jerren, Corrupted Bishop

Can I pay jerrens ability to flip him to the backside with K'rrik. I asked this in my commander game with jerren as my commander and was told I cant do that. To my knowledge Krrik just says for the black in the cost I can pay 2 life, so when I have 13 life I can pay 4 life and 4 mana to fiip jerren over?
