Picking up the baton outside Yorkhill Royal Hospital for Sick Children in Glasgow, the star said she was “very excited” with just two days to go before the opening ceremony.
Crowds gathered to watch the baton travel to the hospital, where it was handed over to Boyle before she took it inside to show to children on one of the wards.
The singer joined in the party atmosphere, meeting fans and dancing to music as she became one of the thousands of baton-bearers to take part in the relay which has been travelling across Scotland for 38 days.
Its final destination will be the opening ceremony at Celtic Park tomorrow evening, where the Queen will read the special message contained inside.
After leaving the hospital yesterday and handing the baton over, Boyle said: “It was a lot of fun and I had a ball, an absolute ball.
“It was good to bring the Commonwealth Games to them because they don’t get a chance to see it, so we’re bringing it to them.”
Talking about the Games, she said: “Bring it on. I’m very excited and very pleased it’s in Glasgow as well.”
But the Britain’s Got Talent star was not giving away any secrets about the opening ceremony, where she will perform among others including Rod Stewart, Amy MacDonald and violinist Nicola Benedetti.
She said: “Watch this space, that’s all I am willing to say.”
Later in the day, the baton was passed to Lord Smith of Kelvin, the chair of the Glasgow 2014 Commonwealth Games, who carried it to Firhill, the stadium of Partick Thistle Football Club.
