However, the Hello hitmaker insists she does still write her online messages, even though they do have to undergo a lot of editing.
She added: "They're all my tweets, no one writes my tweets, they just write them [out] for me. So yeah, that's very, very true."
Earlier this week she opened up about cutting down on alcohol, revealing she did so because "hangovers are torture" when she has to look after her three-year-old son Angelo.
She said: "I used to be able to drink anyone under the table and still be able to put on an all-right show.
"But with kids, hangovers are torture. They just know. They pick up on it and just go for you."
