It was a Beautiful Day for Adam Clayton and his wife Mariana, as they welcomed a baby girl named Alba.
The bassist (57) went down the traditional route by choosing to announce the happy news via a formal newspaper announcement, which read: "Adam and Mariana Clayton are delighted to announce the birth of their beautiful baby girl Alba."
It's not known when or where the baby was born, but the statement came just days after Adam and his chart-topping bandmates performed to a sell-out crowd of 82,000 fans at Croke Park last Saturday.
Either way, it was back to business for the famous musician last night, as he and his bandmates played the first of two sell-out gigs at the Stade de France in Paris.
Clayton and his Brazilian-born wife Mariana (38) have been together for a number of years and married at a registry office ceremony in Dublin back in 2013, holding a second ceremony on the French Riviera at a 14th-century chateau near Cannes.
It was his pal Bono who originally broke the news that the couple were expecting a new arrival - in a very public fashion.
Performing at Twickenham as part of their Joshua Tree tour earlier this month, Bono asked the audience at one point if they thought Adam Clayton was a sexy man.
After they shouted their approval, the frontman then asked Clayton: "Is your sexy woman here tonight?"
When Clayton nodded, Bono said: "And expecting a baby, can I say that?" prompting the expectant father to vigorously shake his head no.
His other half works as a director at the leading art gallery Michael Werner in London and New York.
There's just three more dates left in the band's European leg of their tour before they have a few weeks off, giving Clayton plenty of time to bond with his new baby girl Alba.
Then it's back on the road on September 1, when they return to North America with a string of dates, before they play in Mexico, Argentina and Brazil.
Of Latin origin and with several meanings, Alba is a popular name in Spain, where is means 'dawn'.
When he's not touring, Clayton spends much of the time here at the impressive Danesmoate estate in Rathfarnham, which he has spent years lovingly restoring.
