Emma Watson Makes Sharp Tailoring Look Super Hot For Late Show With David Letterman Appearance

Everyone's favourite British actress in New York Emma Watson made seriously sharp tailoring look super hot on Tuesday for her appearance on the Late Show With David Letterman.

The Harry Potter and Bling Ring star teamed a Saint Laurent skinny black suit with a classic crisp white shirt and Louboutin black pointed slingbacks. Adding a little bit of colour, Watson wore a slick of red lipstick and finished the whole thing off with a smoky eye.

The overall result? Perfect - this is an actress who never goes down the obvious route when it comes to sexy.

Although she's currently on the talkshow circuit to promote her latest film Noah, the thing we REALLY want to know is will she be starring in Sophia Coppola's Little Mermaid as Ariel?

Harry Potter fansite Mugglenet reported last year Watson was in training to take on the part, but it was later revealed to be a hoax.

But that hasn't stopped whisperings in Hollywood, where there's even a rumour Daniel Radcliffe is the favourite to play Prince Eric. W T actual F?

Meanwhile, a source close to the film told The Sun: "Sofia wants Emma, and the pair have such a respect for each other it would be very surprising if they carry on without each other.

"Movie companies Universal and Working Title want to move quickly on this so expect an announcement soon."

Are you excited? Us too - but don't expect Coppola's to be a clean cut remake of the Disney film (except with humans).

Apparently she'll be sticking closely to Hans Christian Andersen's original story, in which Ariel dances for Prince Eric until her feet bleed and then he buggers off with another girl anyway. Typical!
