Ariana Grande has pulled out of the upcoming West End revival of "Sunday in the Park with George," delaying her stage debut. The 33-year-old singer, who is currently on her Eternal Sunshine Tour, will instead take a break from the spotlight once the tour ends this summer, according to her representative. The representative said Grande is stepping back from visibility because of what they described as endless public scrutiny. Grande, a three-time Grammy winner, had been expected to appear in the musical next summer, but her participation has now been called off. No new casting for her role has been announced.
