Singer-turned-reality TV star Dannii Minogue is "going through a really difficult time" as she adapts to life as a single mother, according to her sister Kylie.
The 40-year-old star and her rugby player partner Kris Smith announced last month (Apr12) that their relationship was over, but insisted caring for their toddler son Ethan was their "number one priority".
Kylie now reveals that although her sister is still coming to terms with the split, she is "being pragmatic" and "will be all right".
She tells Glamour magazine, "She and Kris have been amicable, and after heartbreak and disappointment, then it's just organisation, concentrating on Ethan.
"We just have normal sister chats when we can - and that's all you need to know, that your sister's there. If she called me and said, 'I'm really flipping out, I need to see you,' I'd be on a plane tonight.
"But Dannii is tough... Dannii will be all right. Of course she'll be all right."
Kylie also admits her sister was stunned when a new book revealed she enjoyed a secret fling with Simon Cowell, because the news came just days after she announced her split from Smith.
The pop star adds, "It was a bit of a second blow after, 'Oh, my relationship has broken down'."
