Celebrity pictures: Beyoncé and Jay-Z, Salma Hayek, Rihanna

Salma Hayek gets into a spot of bother in today's celebrity gallery.

Having just enjoyed the Alexander McQueen show at London Fashion Week, the actress almost toppled over after getting her heel caught in a metal grid. With eager photographers waiting for that picture, Hayek managed to stay on both feet and laugh off the accident.

Also featured are Beyoncé and Jay-Z attending the NBA game between the New York Knicks and New Jersey Nets - who Jay-Z co-owns alongside Russian oligarch Mikhail Dmitrievitch. The new parents would have left the game happy as the Nets went on to beat their opposition.

Rihanna, Zac Efron, Victoria Justice, will.i.am, Rebecca Ferguson, Kim Kardashian, Evan Rachel Wood and Jamie Bell can also be found in the gallery below:
