Ex S-Clubber Rachel Stevens showed up at the St Trinians World Premiere in London Monday night looking sexy but certainly not school-girlish in her bootcut jeans, delicate beige camisole and luxurious black velvet blazer.

The heavy fabric of the jacket and light cami contrast perfectly while her black and gold clutch look very sophisticated.

It looks like her top needed hoisting up a little though, her bra's playing peek a boo!

And what does Rachel do these days? Other than randomly turn up at celebrity events every now and again?
