Majella O'Donnell is the picture of pride as she cradles her new granddaughter Olivia Margaret Lynda Shields.
Majella's daughter Siobhan gave birth to the bundle of joy on Sunday evening at 5.44pm.
"Mum, dad and baby doing well," Majella (54) told her Facebook fans.
"So delighted and blessed to have her. Welcome to the world Olivia Shields."
Speaking of her and husband Daniel's (inset) excitement recently, Majella said: "We're so looking forward to being grandparents.
"I've a room done up for when they visit. We're so excited, we can't wait."
Majella's 27-year-old daughter is engaged to long-term partner Gavin Shields, who popped the question last Christmas.
Majella previously admitted she was keeping the month of August free so she could spend quality time with her daughter and granddaughter.
It's been a busy few weeks for Majella and Daniel, as the pair recently finished filming their new reality TV show, Daniel and Majella's B&B Road Trip.
The show, which will be aired on UTV Ireland from October, follows the couple as they tour a variety of Bed and Breakfasts across the country.
Their B&B hosts will act as tour guides, showing the couple around the local area.
Majella and Daniel started off in Lough Key Forest Park, Co Roscommon, before heading to Loop Head, where they took part in a fishing trip.
At each location the couple are given a surprise challenge.
"I see it as a travel show," Daniel said before they started filming.
"It should be good fun. If it works it works, and if it doesn't then we'll never speak about it again."
UTV Ireland have been inundated with requests from B&B owners asking if Majella and Daniel will consider visiting.
