With great sadness, I must report that Helena and Tim have confirmed that they split up earlier this year:
“Tim Burton and Helena Bonham Carter separated amicably earlier this year and have continued to be friends and co-parent their children,” Burton’s rep tells E! News in a joint statement. “We would ask that you respect their privacy and that of their children during this time.”
Edit: Neither Helena nor Tim have specified a reason for their separation. Sites claiming to have ‘sources’ who provide speculation about the couple’s relationship and personal lives are deliberately spreading rumours and false information in order to create more drama. These rumours are unfounded and highly likely to be false.
