ARIANA GRANDE: Petal (Babydoll)Verdict: Bruised but unbowedRating: Three out of five starsWhen Ariana Grande announced last weekend that she was pulling out of next year's London stage production of the Stephen Sondheim musical Sunday In The Park With George, it was easy to understand her reasoning. The American superstar has grown up in public since releasing her first album, Yours Truly, as a 20-year-old wannabe in 2013. Florida-born Grande, 33, has described this as her 'experimental' album – one coming from a place of 'unfiltered rage'. There's a giddy love song in Stay, gentle innuendo on Big Feelings, and a blunt message to her exes on Oh Well. Ariana Grande starts a residency at The O2, London, on August 15 (axs.com).
