The Rolling Stones legend shared a hilarious photo on Twitter as he took a nap in his wife Sally's hospital room, alongside his newborn daughters Gracie Jane and Alice Rose.
The 69-year-old, who also celebrated his birthday last week, didn't seem to notice the window cleaner as he rested.
The worker gave a cheeky thumbs up at the camera as he got to work in the impressive London location.
"While I was sleeping with the twins," Ronnie, who was seen curled up on his side, told his 443,000 followers.

The crooner, who wed his third wife back in 2012, revealed the happy news via his publicist seven days ago.
"Ronnie & Sally Wood are delighted to announce the birth of their twins Gracie Jane (6lb) & Alice Rose (5.7lb)," a statement read.
It continued: "The girls arrived on May 30 at 10.30pm and all are doing brilliantly. The babies are perfect."
Pal Rod Stewart, who also became a dad again later in life, tweeted: "Congrats @ronniewood and @SallyWood. Your life starts all over again now, trust me, I speak from experience!"
Ronnie's latest additions to his famous family came just days before his mum's birthday, when he posted a tribute online.
"God bless my mother Mercy Leah Elizabeth, it is her birthday today, she would have been 105-years-old," he stated.
