Beyoncé Knowles is the face of Samsung's F300 Ultra Music handset. The actress and Destiny's Child will appear in ads promoting the phone, and the South Korean giant will sponsor her latest world tour, which kicks off its European leg next month.

Buy an F300 from April and you'll even get a pre-loaded copy of the spirited songstress' latest hit, Irreplaceable, Samsung said.

The F300 is a tri-band GSM/GPRS/EDGE handset with a two-megapixel camera, an FM radio, mulit-format music player, Bluetooth wireless stereo and 100MB of on-board song storage - expandable using Micro SD cards. It boasts a 'double A-side' dual face, with controls front and back.

Samsung said it was "thrilled" to be working with Beyoncé because "we share a lot in common... We both aspire to deliver seamless satisfaction", whatever that is.
