The 36-year-old is said to be "over the moon" after she and hubby Rob White welcomed their first baby into the world just in time for Mother's Day.
The bundle of joy was born at Dublin' Holles Street Maternity Hospital yesterday.
The Tipperary beauty and her businessman husband said they had “welcomed their baby girl into the world at 12.40pm”.
Andrea, who won Miss Ireland in 1998, was previously married to businessman PJ Mansfield and married Rob in Ibiza in 2012.
Rob described himself as “the proudest father” and said mother and baby were “doing great”.
