Angela Scanlon is expecting her first baby, and announced it with a series of online posts.
The Robot Wars and One Show star (33) took to Instagram to share the happy news with her fans.
She posted a picture of herself with the caption "I've been baking for 6 months... and I've made a bun! It's in the oven & will be ready by springtime.
"We are so, SO thrilled ... and can't wait to welcome a mad, wonderful little human into our world."
"Really hoping he/she is ginger," she added, before posting a picture of an orangutan with the comment: "Apart from feeling severe resentment at the lack of promised glow we are so, SO delighted...plus, my hair looks great."
Angela is expecting her baby with her husband, Rory Horgan, who she married in 2014.
She has co- hosted the BBC's reboot of Robot Wars with Dara O Briain since August last year.
Angela fronted the BBC's topical teatime programme The One Show alongside Matt Baker while Alex Jones was on maternity leave earlier this year.
She still occasionally fronts The One Show when Alex takes time off.
RTE star Jennifer Zamparelli was one of the first to congratulate her pal, saying: "Ah that's lovely news, congrats".
Kildare comedian Aisling Bea said, "Let it be known I knew before you did, so can technically put me down as the father."
