Jennifer Lopez has taken to Instagram this week to show us her brand new short and choppy ‘do.

While Jenny from the Block has sported a lob for some time now – her latest selfie shows that she’s entered Phase Two of her short hair plan.

Yeah, we love it.

Meanwhile, Ginnifer Goodwin has switched up her usually brunette 'do for a daring pastel colour this week.

The 37-yearold actress, who  underwent eight hours of bleaching to achieve a striking lilac hue, told US Weekly that the transition was "a whole big thing - but it was worth it."

Some subtle hair transformations are proving to be just as eye-catching, however.

Cinderella - ahem, Lily James - has recently traded in her golden locks to join the brunette brigade. The English actress (who you may also recognise from Downton Abbey) stepped onto the Comi-Con red carpet this week with auburn brown tresses.
