Alex Jones has claimed she never has to fake her good mood or friendliness on TV.
The One Show presenter admits she has a reputation for always being friendly and "nice" and insists that is not put on for the camera.
Jones, 46, told The Guardian: "Whatever mood I am in, good or bad, I have to host The One Show, but I never feel like I have to be 'on' or to fake any kind of sunniness. Our team has such a laugh in the pre-show meeting that I always feel better by the time we are on telly."
She added: "In fact, work is a bit of a break these days because I have three kids. TV is a walk in the park compared with being at home!"
The Welsh presenter is often the subject of jokes about her cheery personality on the BBC show and her ability to smile through out.
She said: "I am probably known as 'the girl next door'. While I am a little bit more feisty than people might think – certainly my husband would agree with that – I don’t think my friendly reputation is a bad thing.
"Given what other people go through, I feel lucky that the biggest assumption about me is: 'Alex off The One Show looks like she’d be quite nice.' "
Jones returned to the show last year after taking maternity leave when she welcomed 20-month-old daughter Annie, her third child.
She is also mother to sons Teddy, five and Kit, three, with her husband Charlie Thomson.
The former Strictly Come Dancing contestant, who has hosted The One Show since 2010, married her husband in 2015 and was worried that at 38 she had left it too late to conceive.
She opened up about her own fertility struggles in BBC Two documentary Alex Jones - Fertility & Me. She fell pregnant with her first son Teddy in 2016.
