Jessie J shops at flea markets.

The singer clearly isn't worried about the 'Price Tag' of her outfits since she was spotted browsing for bargain buys at a second hand market stall in London.

According to the Daily Star newspaper, a source said: ''We couldn't believe it when we saw Jessie shopping. She was having such a good time rummaging. Jessie was chatting and bartering with the stall owners and she certainly knows how to grab herself a good bargain.''

The 25-year-old singer decided to tone down her look last year after deciding her catsuit-wearing phase was a bit too aggressive and sometimes made her resemble a ''clown''.

She previously explained: ''I think I'm still edgy and I still take risks. I still wear high-waisted knickers on stage with a little crop top, but I don't want to be a clown. I think I've definitely evolved into being a bit more presentable.

''I sent [old pictures] to all my friends the other day and said, 'If I ever dress like this again, don't let me out of the house'.''
