We've heard of brothers teasing sisters but not like this!
It started with:
According to the source, Katie's daughters Ellie and Carrie didn't think that Brooks "could 'measure up'" to their late father Jay Monaha, who passed away due to colon cancer back in 1998.
Whether or not that was the main reason of the break-up, we can understand how it could be difficult for Katie's daughters to adjust to a new father figure in their lives, and we're sorry that things didn't work out.
What do U think? Was the Katie/Brooks break-up influenced by Ms. Couric's daughters???
