U2 bass player Adam Clayton has welcomed his first child with much younger wife Mariana. Announcing the birth of his little bundle of joy, Clayton came up with a personal advertisement for The Irish Times.

On Tuesday, the ad was circulated by the publication. It read: “Adam and Mariana Clayton are delighted to announce the birth of their beautiful baby girl Alba.” This is the first child of the couple who has a 19-year age gap — Clayton is 57, while Mariana is 38.

This may be the first baby for Mariana, but it isn’t for her husband, who is already a father to a boy born in 2010 from a previous romance with an unnamed French woman. The birth of Clayton’s first child made him the last U2 member to be a parent.

Prior to the revelation that he had fathered a son, Clayton appeared to be very content with the single life and not having kids. However, things abruptly changed after the birth of his first child. A source close to U2 told the Independent in 2011 that Clayton was “deliriously happy with fatherhood.”

Prior to meeting Mariana, Clayton was known for being the boyfriend of supermodel Naomi Campbell. The two were even engaged, though it was shortlived. Clayton never married until he met Mariana. The English-born Irish musician and the Brazilian beauty tied the knot in 2013 twice. First, they married in a registry office in Dublin, Ireland, then they walked the aisle in the the French Riviera at the 14th-century château in Mandelieu-la-Napoule near Cannes, according to Daily Mail.

On July 8, Clayton’s bandmate Bono announced during their Joshua Tree Tour at Twickenham Stadium in London that the bassist was expecting his first child with his wife. Amid the arrival of his first daughter, Clayton is set to go on a sold-out 2017 tour with the band. They are currently touring Europe, then they will fly to the United States before heading to Mexico and South America for their other tour stops.

The baby news comes a month after Clayton was honored with the Stevie Ray Vaughan Award at the MusiCares MAP Fund concert in NYC. During his acceptance speech, he thanked his bandmates. “I was lucky because I had three friends who could see what was going on and who loved me enough to take up the slack of my failing,” Clayton was quoted as saying by ET Online.
