Ronnie Wood has welcomed his fifth and sixth children!

The Rolling Stones guitarist, 68, and wife Sally, 38, announced the births of their twin daughters on Monday evening.

“Ronnie & Sally Wood are delighted to announce the birth of their twins Gracie Jane (6 lbs.) & Alice Rose (5.7 lbs.),” Wood’s publicist confirmed in a statement to BBC News. “The girls arrived on 30 May at 22:30 and all are doing brilliantly. The babies are perfect.”

New mom Sally took to Twitter on Tuesday to thank her followers for the support and well wishes. “Thank you all so much for the [hearts] ~ can’t believe our babies are a day old already. They are wonderful xx,” she tweeted.

On the eve of the arrival of his baby girls, Wood tweeted a smiley selfie with the caption, “Waiting #38weeks+,” just a couple weeks after talking about becoming a father again.

“I’m getting excited about the arrival of my twin girls sometime in the next few weeks,” he wrote on May 15.

In December 2015, a rep for the singer confirmed to PEOPLE the couple were expecting twins. Gracie Jane and Alice Rose are the first for Woods’ theater producer spouse.

The rocker, who is a grandfather of 10, is already a dad to four adult children — Leah, 37, Tyrone, 32, and adopted son Jamie, 41, from his second marriage to Jo Wood, and Jesse, 39, with his first wife Krissy Wood.
