This 22-year-old pop star is signed to Jay Z's Roc Nation label and this will be her second appearance at T in two years. She's fast becoming a style icon too and is the new face of Madonna's clothing line. Her debut album O.R.A spawned three number one singles "Hot Right Now", "How We Do (Party)" and "R.I.P." featuring (Tinie Tempah). Rita is now working on her second studio album which she says will showcase a different side of her. Nevertheless when she takes to the main stage at T the party girl is sure to be in full force.
