Jessie J: Shaving my head 'a massive highlight'

Jessie J says shaving her head was a highlight of her fame so far.

The 'Wild' singer has experienced a whirlwind two years since releasing debut album 'Who You Are' in 2011 and is still awestruck at all she has accomplished in a short period of time although she is particularly proud of her charitable sacrifice in March.

Jessie - who shaved her head to raise money for Comic Relief - said: "Obviously, shaving my head was a massive highlight.

"I've been wanting to do it for a long time but I wanted to be famous enough that it would raise a lot of money."

The 25-year-old star - who raised £500,000 for the charity with her stunt - is also pleased with her other accomplishments over the past 24 months, including performing at the London 2012 Olympics closing ceremony and appearing on BBC show 'The Voice' as a mentor.

She told the UK's Glamour magazine: "The Olympics last August were unreal, it feels like yesterday and it was the most exhilarating feeling to be part of Britain's history.

"The [Queen's Diamond] Jubilee, obviously, was a huge moment, too.

"Being back on 'The Voice' [has also been a highlight], and writing my second album has been a huge thing. It's been really challenging but I'm really proud of myself."
