CBBC star Mark Speight is "absolutely distraught" after the death of his girlfriend on Thursday.
The SMart presenter was arrested in connection with her death but he said he had nothing to do with her dying.
He has been released by police and they say that once they've carried out further investigations they will talk to him again in February.
It's normal for police to question people when someone dies and they don't know the cause.
But it doesn't necessarily mean any crime has been committed.
Presenter Natasha Collins
His girlfriend, Natasha Collins, was found dead in the bathroom at their flat in London on Thursday. She was also a performer and presenter.
CBBC has cancelled Saturday's episode of SMart.
Mark has presented the show since 1995.
