British boyband Lawson played a gig in leopard print catsuits and black bob wigs in honour of singer Jessie J, who shaved her head for charity on Friday (15Mar13).

The pop group shocked fans with their outrageous outfits when they took the stage at Cardiff University Great Hall in Wales on the same night Jessie J shed her locks on live Tv as part of Britain's Comic Relief telethon fundraiser.

Lawson then took their tribute stunt one step further - by performing a version of her hit song Price Tag.

Frontman Andy Brown tells Britain's The Sun it was actually Jessie J who dared them to try out her trademark look to help raise even more money for the cause.

He explains, "We love Jessie. She raised an incredible amount for the charity and we wanted to do our bit as well. I'm not sure the catsuits will be back again. We don't look as good in them as she does. But it was a good laugh for a great cause."

A record $120 million (£75 million) was raised during the Comic Relief festivities this year (13).
