Television presenter Glenda Gilson and her husband Rob MacNaughton are celebrating the birth of their first child.

The couple's son, Bobby, was born on Monday night in Dublin with his father writing on Instagram: "Bobby Mac arrived into the world at 11.16pm weighing 7lbs. Both mummy and little man doing well & Daddy over the moon."

Xposé host Gilson announced she was expecting in April, writing on Instagram: "Excited to let you know myself & rob are adding to our little family." 

"We're both so happy and feel so blessed that I'm pregnant," she continued.

"Hopefully our baby won't be as hairy as [the couple's dog] Yazz."

Gilson and businessman MacNaughton married in 2014 after three years together.
