Olympic-winning athlete Bruce Jenner is reportedly unhappy with teenage daughter Kylie's alleged affair with 25-year-old rapper Tyga.
Bruce, 65, who finalised divorced from reality TV star wife Kris last month after 23 years of marriage, is worried about the way Kylie, 17, is leading her life without adequate parental supervision, reported Radar Online.
"For the longest time, Bruce kept the divorce amicable. But now that it's finalised, he's ready to stop stepping back. It's killing him to watch her (Kris Jenner) look the other way as (Kylie and Kendall) date older guys and make one bad decision after another," a family insider said.
