Dannii Minogue and Kris Smith have taken to Twitter to comment on their separation. Dannii took to the social networking site first, writing on Wednesday morning Australia time: "It brings me great sadness to tell you that Kris & I have separated. We still care for each other & ask for privacy at this difficult time, in particular for our son Ethan who remains our number one priority." A few minutes later she wrote: "Hi Tweet peeps. Needing to retreat for a while. Thank you for your ever loving continued support." Kris then wrote on his own Twitter page: "Dannii and I have a deep mutual love and respect for each other and although things have not worked out we have a gorgeous son together that we both love and implore everyone to respect our privacy at this challenging time."
