Kris Smith split from Dannii Minogue because he was tired of her parents being around.
The former rugby player was reportedly upset at Dannii's parents Ron and Carol constantly being with them and their 21-month-old baby, Ethan, according to a close friend.
The source told the Daily Mirror newspaper: "Kris is just an easy-going guy.
"He's not up for all the stuff that goes along with being part of the Minogue corporation."
Dannii and Ethan have been staying with Ron and Carol in Australia since the split became public earlier this week.
