And now, friends of the couple have come forward to reveal why the couple’s two-year marriage ended so abruptly.
'There's no doubt they still love each other very much and they're in a good place,' one of the 'shocked' friends told News Corp.
The unnamed friend said they'd 'caught up' with both Emma, 28, and Lachlan, 32, last week.
The yellow and purple Wiggle announced their split with a statement to The Daily Telegraph yesterday.
They told the publication, 'We have, and continue to share, the most beautiful life together, but we wanted to let you know that privately for the last six months we have been navigating through a trial separation, and we have made the decision to separate as a couple.'
'Throughout that period, we have performed hundreds of shows together and that is always a continued source of joy for us both.
'We have embraced this as a very positive change in our relationship. Our incredible friendship has been strengthened throughout this time and what we have discovered is that, more than ever, first and foremost we love and adore performing as Emma and Lachy in The Wiggles and having the privilege of celebrating this happiness with extraordinary families around the world.'
The star’s continued, 'We have chosen a different path to travel in our personal lives, but please know that we are stronger than ever and we can’t wait to see you at a show soon. We will not be commenting beyond this, and we thank you in advance for respecting our privacy.'
The news came as a huge shock to fans, with neither Emma or Lachy giving any indication as to the problems in their marriage.
'They were very happy and affectionate so it came as a complete shock,' the friend continued.
'There's no doubt they still love each other very much and they're in a good place, they just feel they'll be better as best friends.'
