London, May 30 (IANS) Singer Dannii Minogue seems to be going through a rough patch in her love life with model Kris Smith.

According to a source, the couple have had a series of fights and are struggling to balance family life and their busy careers, reports dailymail.co.uk.

The singer also hinted at the strains in a few messages on Twitter.

‘Never chase love. If it isn’t given freely by another person, it’s not worth having,’ she posted.

In another message, she wrote: ‘Forgiving someone does not mean forgetting what they did. It simply means letting go of the hurt.’

Smith, who is also a former rugby player, also hinted at trouble in their paradise.

‘You don’t know what you’ve got til it’s gone.’

However, the posts were deleted later.

The reason behind the fights happens to be Minogue’s career, and her lack of focus on their son Ethan, who turns one in July.

‘Kris is not happy about Dannii’s heavy work-load, and wants her to spend more time with him and baby Ethan, and has put his foot down,’ a source told News of the World.
