Myleene Klass is pregnant with her second child.
The 32-year-old TV presenter - who recently revealed she and fiance Graham Quinn have temporarily put their wedding plans on hold - had her three-month scan last week which confirmed her "happy" news.
The pretty brunette tweeted: "Woo Hoo! I'm pregnant! So happy! x (sic)"
Myleene is now preparing to give birth in March next year, but is currently suffering from terrible morning sickness.
She tweeted: "For everyone who's asked... March is the 'big month'. Four fire signs under one roof. Crikey!
"Head in sink most of morning! Lovely."
Myleene, who has a three-year-old daughter Ava with Graham, has always said she planned to have a big family.
The TV star recently joked she would like to give the tot seven siblings, after Ava asked for two sisters.
She said: "Ava said to me the other day, 'I miss my sisters'.
"I said, 'Oh really? How many sisters do you have - or do you want?' She said she'd like two. I'd love her to have seven sisters. I don't think I could love anybody as much as I love Ava, but I have two siblings and I don't feel my mum loved any of us less (than the others)."
Although only confirming the news this weekend, Myleene apparently hinted at pregnancy cravings when she tweeted about a photo shoot for Marks and Spencer earlier this month.
She wrote: "Been shooting M&S tv xmas bits. Have eaten my own body weight in mince pies and turkey stuffing and we're still in September! (sic)"
As well as having a baby, Myleene is also concentrating on battling to keep her job on next year's 'Popstar To Operastar'. ITV bosses can only afford one presenter and need to choose between her and Alan Titchmarsh.
