The hottest trendsetters today are getting bored of their blonde balayage locks and going for something more striking - siren red hair.
At the annual White House Correspondents' Association Dinner last week, Scarlett Johansson made an entrance with a stunning auburn long bob.
Another new star to show off rich auburn tresses is Blake Lively, the former perennially golden blonde star of Gossip Girl.
Blake wowed onlookers last week at the 2011 Time Magazine 100 Most Influential People party, saying she loved her new look, which is for an upcoming film role.
Also making a switch after years of blondness is Whitney Port, formerly of The City, who debuted fresh strawberry blonde curls at a reality stars event in early April.
She's in good company - both Drew Barrymore and Mandy Moore have switched from boho blonde to coppery locks this year.
Tip: If you are considering making a major hair colour change like this, it's usually best to see your hairdresser first. But once you've settled into your new hue, it's easy to keep it up thanks to home hair colour kits.
These five stars are new converts to the red side but see who else is established as Hollywood's hottest redheads here.
