Christine Baranski celebrated a night out on Broadway in style. The Gilded Age actress, 73, stepped out at the re-opening of Mamma Mia! at New York City's Winter Garden Theatre on Monday, Aug. 18, wearing a disco-inspired silver sequined suit and was photographed holding hands with singer King Princess, 26.

In the first picture, Baranski, 75, posed in a shimmery silver suit as she wrapped an arm around King Princess, 26, who wore a newspaper-inspired button-down blouse with black trousers. The singer-songwriter cheekily captioned the photo with a hashtag that reads: “Love is Love.”

Christine Baranski and King Princess sparked dating rumours this week after they were spotted holding hands on the red carpet for the Broadway reopening of Mamma Mia.
