Rory REVEALED WHY he rejected £12m FedEx Cup jackpot to be at the birth of his daughter
The FedEx Cup is a play-off to determine the winner of the PGA Tour.
McIlroy and American Stoll kept the pregnancy a secret.
But they have revealed all now after a TV commentator unwittingly let slip Erica was due to give birth.
The four-time Major champion disclosed the news during the BMW Championship in Chicago.
McIlroy, 31, married Stoll at a lavish reception at Ashford Castle in County Mayo in Northern Ireland in 2017 attended by soul legend Stevie Wonder and Coldplay singer Chris Martin.
The pair met when Erica worked for PGA with Stoll famously helping McIlroy make his Ryder Cup tee-time in 2012 after oversleeping.
They started dating in 2015 and got engaged that December while on holiday in Paris.
He was previously with tennis star Caroline Wozniacki.
McIlroy, who previously criticised USA President Donald Trump’s handling of the coronavirus, confirmed the news after completing his round on Saturday.
He said: “We’re about to be parents very soon, so we’re obviously super excited.
