MIRIAM O'Callaghan has forsaken the cosy confines of the RTE studios this week to take to the wilds of Donegal to film a new TV documentary.
The award-winning Prime Time presenter may be edging closer to her 50th birthday -- but is showing no signs of slowing down.
The Herald can reveal how the hard-working mum of eight (49) is travelling around the north of the island, to Belfast, Derry and Donegal, as she works on a new TV project.
However, she was giving nothing away when quizzed on the intricate details of the documentary after posting up pictures on her Twitter page of her and her camera crew filming in various outdoor locations.
"It's still top secret what the documentary I am working on is about -- but will become obvious next week," she wrote. "Working with a great team though, so we'll have fun."
Writing about one picture of her taken at Lough Swilly in Donegal, she describes the picturesque area as "beautiful, even in the lashing rain".
She is expected to spend the rest of the week filming for the new show before going back to Dublin to film her Saturday night chat show. The new documentary harks back to the past for Miriam, who previously co-owned Mint Productions with her Belfast-born hubbie Steve Carson, where they held the titles of executive producers.
Founded in 2000, the company has been responsible for such popular shows as Who Do You Think You Are and the documentary series on former Taoiseach Bertie Ahern.
However, the high-profile couple decided to wind up Mint following Mr Carson's appointment as RTE director of programmes.
