He told American newspaper USA Today: 'I don't have any thoughts on any of it.
'I don't know what people are saying. I'm not the one to speculate on timing.'
The 37-year-old has been too busy planning his wedding to notice any of the speculation that has been said about it.
Nick said: 'I'm very excited. We haven't really planned anything yet. We're still newly engaged so we'll get to all that.'
But for the time being Lachey is focusing on his Christmas plans.
He added: 'I'm a big believer in spending it with the family.
'For me it's all about being with your loved ones. I'm going home to Cincinnati to see my niece, nephew, parents and grandmother.'
