A couple of big UK-based celebrities took their support of Red Nose Day 2013, a telethon aired to help raise money for charity Comic Relief, to new heights — and to one in particular, a new (but amazingly awesome) low!

The boys of One Direction (who’ve done quite a bit for the charity, including the release of a documentary of their time in Africa via iTunes) were part of the celebration with member Louis Tomlinson sporting a bright red ‘do for the day.

But it was pop singer Jessie J who probably underwent an amazing transformation to bring awareness to HIV/AIDS: she shaved her black locks completely off.

Before her big cut, Jessie met with those who had been helped by the organization, including men and women effected with HIV and girls who’d been the victims of sex trafficking. The 24-year-old tearfully said that shaving her head “is the smallest thing that I could do to give back to these people that need it so much.”

So how does she look now? Well, you can check that out after the jump, along with a clip of her getting clipped and a pic of Louis from 1D with his new ‘do as well!

And in case you were wondering, Comic Relief has raised £75.1 million as of  last night — a new record for the charity!
