The 48-year-old "Spinning Around" hitmaker is said to have settled down in a serious relationship and living in a right atmosphere, reported Female First.
"It's all starting to come together for Kylie, she's in such a good place," a source said.
Revealing Minogue and Sasse share a strong bond, the source added, "She never really made a big deal about motherhood when she was single but now she's in a very serious, long-term relationship, it's on the agenda. Her family and friends are just as excited for her."
The Australian-born songtress and the "Galavant" star confirmed their engagement earlier this year after dating for six-month.
