Taking a short break from parenting duties for baby Willow, Pink
and husband Carey Hart
visited the early show of O
by Cirque du Soleil at the Bellagio Las Vegas.
Accompanied by four friends, the pop star and her group arrived to the show after dining on sushi at Yellowtail. "Pink sipped on a glass of wine during the show," an onlooker tells PEOPLE, adding that it was her first time seeing O.
But the fun didn't end there. The following night, the superstar and motocross pro took in a late performance of Zumanity – The Sensual Side of Cirque du Soleil
at New York-New York Hotel & Casino.
Accompanied by a group of friends, they had to make their way directly back to their hotel following the show so Pink could have some mommy time with daughter Willow.
According to an onlooker, she said, "This is the latest I've stayed out since [the baby]."
Mid-show, Hart enjoyed a glass of red wine during the show while Pink and friends stayed hydrated with bottled water.
