'My biggest bump yet!' - Pregnant Karen Koster shares behind the scenes snap
Karen Koster has marked the impending arrival of her third child with a behind the scenes picture of her "biggest bump yet".
The Xpose presenter (36) and husband John McGuire are already parents to Finn (3) and JJ, who is celebrating his second birthday today and she announced last month they are expecting their third baby
Taking to social media, she shared a photo of herself on the set of the TV3 entertainment show, wearing a billowing polka dot blouse and black skinny jeans.
"Think this is going to be my biggest bump yet. And three weeks to go," she wrote.
Some of Karen's tv friends sent their best wishes, including model Michele McGrath, former Xpose co-host Lorraine Keane and RTE host Maura Derrane.
Announcing her pregnancy in January, she told how she and John were excited to expand their family, but admitted it has not been all plain sailing.
"I'm very happy and very hormonal. It's been a really magical Christmas thinking, 'Wow, we're going to be a family of five'," she said.
"The pregnancy has been more of a challenge this time, though, probably with being older and having two kids already to run around after."
And she reckons Finn and JJ will take well to their new brother or sister.
"This baby is going to be coming into a family with two boys who are great craic, so I know they're going to have a good time," she said.
Karen recently branched out from Xpose when she hosted TV3's one-off documentary Mummy Guilt, which explored how mothers juggle their work commitments with their home lives.
"I'd lots of doubts while I was making it about lots of different aspects, but I'm so proud of the end result," she said.
