Spot: Once again, celebrity fashion online manages to surprise us when we least expect it!. Not too long ago, we saw blue-haired Katy Perry looking all futuristic and shiny in a Paco Rabanne dress at the Echo 2012 Awards in Berlin, and I said I would share when the dress arrived online. Well, that time is now.. and we have to be quick, as it already sold out at one of two online boutiques!

Spot: Perhaps it's time we resign ourselves to Katy Perry's blue hair, it looks like it received a fresh rinse for her appearance at the 2012 ECHO Awards in Berlin! She was also sporting a fresh cartoon-like updo, is this another tribute to her Smurfette character..? And shall we speculate how long this colour will last? My money is on April 1st - we won't see it after that date.. stay tuned..

Hair aside, she gleeeeamed in some kind of silver in this Paco Rabanne dress from Spring/Summer 2012 - silvery squares in assorted sizes - it's

Spot: We have more celebrity fashion here, courtesy of Katy Perry during her quick London trip, as she was snapped leaving the BBC Maida Vale Studios on Sunday evening. She graciously stopped for fans, and definitely looked more at ease here, compared to her dinner the night before at Nobu (which may have just been overwhelming paparazzi, not memories of happier times in London).

And where there is a shopping spot, I'm here to share!

We're talking about the gorgeous

Spot: Katy Perry was anything but all smiles as she was snapped leabing Nobu restaurant last night.. and perhaps she has moved on, but I couldn't help but be reminded of how happy she was on previous trips to London. Whether it was attending the theatre with her mother-in-law, or looking all loved up with Russell Brand back in the days when they were inseparable. It may just be that the paparazzi was hovering too close, but either way, she doesn't look too happy..

Anyway, fashion is why you're here - Katy

Spot: Heading back to Paris for a moment - before Katy was a knockout in electric blue arriving at the Viktor & Rolf Autumn/Winter 2011 collection, she spent one day in two rather fabulous outfits.. one of the VERY major (and a dress we have seen on the site before, albeit modified).

She started her day looking super feminine and rather sophisticated in a light mint dress by Vera Wang - from the Spring/Summer 2012, the dress has a sheer skirt (for real, it's completely sheer!) and a laser cutout top. This is chic, but very daring.. and what else do you carry in Paris but the Hermes Birkin bag..?

She did a quick change later 

Spot: Katy Perry is no stranger to Paris Fashion Week, in fact it may have been one of her first public outings with new-boyfriend Russell Brand a couple of years ago. What a dramatic romance that turned out to be..

She was snapped arriving at the Viktor & Rolf show dressed head to toe in blue.. and I mean that literally, as she is still sporting the blue 'do. OK, I don't much care for the colour (she isn't a teenager), but I absolutely LOVE this hairstyle on her. I'm sure I'm not the only one, so here is a close-up for your stylist (just go easy on the blue!).
