Wearing a sombre suit and dark tie, Hollande was asked about his "Monsieur Normal" image and the Twitter row.
"I am for a clear distinction between public and private life. I believe private matters should be regulated in private and I have asked those close to me to respect this," he said.
He also explained there would be no official "first lady" status for his partner. "Valerie wants to keep her professional activity and I understand that. However, she will be at my side when protocol demands."
Most of the interview was spent discussing France's economic concerns.
Hollande defended his record during his first weeks in power. "I have defended the interests of France at the G8 in Washington; afterwards I was at Chicago to announce the withdrawal of French troops from Afghanistan; I have participated in two European summits, so I have fully respected the [political] engagements I made to the French."
On the announcement by carmaker PSA Peugeot Citroen that it planned to shed 8000 jobs, Hollande said: "It's a shock, particularly for the workers concerned by this brutal announcement. The state cannot remain indifferent."
He said he believed the company had delayed the announcement until after the election, "perhaps as a service to those then in power".
"This plan was not announced when it was foreseen and it was delayed until after the election. Now we have to do something about it. It is unacceptable."
