Supermodel Agyness Deyn can't seem to do any wrong recently - and yesterday proved no exception.

The 25-year-old, currently the most in-demand model on the planet, wowed 45,000 ecstatic fans when she sang with New York band Five O'Clock Heroes at the T4 On The Beach party.

Agyness looked in her element as she took the stage and launched into Who, her recent single with the rockers.

And offstage, the Lancashire lovely caused a stir as well, by arriving with her new boyfriend, The Strokes guitarist Albert Hammond Jr.

The couple went public with their relationship at the Songwriter Hall Of Fame Awards in New York last month.

It came just weeks after Agyness split from The Paddingtons rocker Josh Hubbard, whom she had dated for four years.

Among the 28 acts to perform at the Weston-Super-Mare, Somerset event were Duffy, former Destiny's Child star Kelly Rowland, The Feeling, McFly, Sugababes, Feeder and Sam Sparro.

Police warned revellers attending the one-day festival that alcohol and glass wouldn't be allowed on site.
