Celebrity pictures: Katy Perry, Sarah Jessica Parker, Mary Berry

Yesterday (April 19), Katy Perry attended the ASCAP I Create Music Expo. The singer revealed at the event that she is halfway through recording her new album, and also spoke about reuniting with pop supremo Dr Luke.

Sarah Jessica Parker could almost have been filming a scene from Sex and the City as she hailed a taxi in New York. The actress stood in the street against the city's backdrop as photographers snapped away.

Mischa Barton, Paris Hilton and Jessica Alba attended the second weekend of Coachella, while Heather Graham and Zac Efron arrived for the premiere of At Any Price, a movie thriller directed by Ramin Bahrani.

In London, Tamara Ecclestone and Jay Rutland dined at Nobu, Katherine Jenkins and Il Divo performed at the O2 Arena and The Great British Bake Off judge Mary Berry signed copies of her book At Home.
