The 33-year-old Grande had been slated to star opposite her Wicked castmate Jonathan Bailey in the Stephen Sondheim musical Sunday In The Park With George in the summer of 2027 at London's Barbican theatre. She began her career as a teen on Broadway before embarking on a hugely successful pop career. Her star turn as Glinda in the film adaptation of Wicked earned her an Oscar nomination for best supporting actress. But the massive success of the film and its sequel Wicked: For Good meant Grande was doing constant media appearances for the better part of two years. She is set to appear in the comedy Focker-in-Law opposite Ben Stiller and Robert De Niro, which hits theatres in November.
