Britney Spears has gone from a short bob to long hair with dip-dyed ends. Nice.

“I think I did it again…”

That’s the opening line to Britney Spears‘ 2000 hit Oops!… I Did It Again, but it applies rather well to her hairstyles of late. Allow us to talk you through it.

So, last month the 33-year-old chopped her blonde hair into a chin-skimming, long-layered bob which caused much excitement among her Instagram followers:

Bob Town, population Brit.

Now, with the help of extensions she's been back to her longer style for a few weeks, which makes us wonder if she suffered a bit of post-chop regret. Hey, we've all been there.

However, the mum of two has just added another new twist to her look. Spears shared a vacation snap from Hawaii overnight, and if you look closely you can see her ends are purple — which is convenient, because her bikini of choice is also the colour of lavender.

Where possible, always match your swimwear to your hair colour, right?

Although Spears didn't mention her dip-dye in her caption, her followers were quick to detect it. Our two cents? It looks great. Go Britters. We eagerly anticipate your next big hair shake-up.

Speaking of hair shake-ups, another celebrity has been tweaking her 'do. (Post continues after gallery.)

Actress Jenna Dewan-Tatum debuted a shoulder-length bob on Instagram a few weeks back, and it seems she'll fallen under the 'once you chop, you can't stop' spell.

Thanks to celebrity stylist Jen Atkin, 34-year-old Dewan-Tatum — who, as you might already know, is married to Magic Mike star Channing Tatum — now has a more choppy, asymmetrical style.

According to Atkin's Instagram caption, the gorgeous new style was inspired by model Daria Werbowy.

Dewan-Tatum is one happy customer — on Instagram she described this as "the best new haircut". We'd be pretty stoked, too.

Clearly, the short hair trend is showing no signs of slowing down — although there are still some A-list women who are holding out. We're waiting for the stubbornly long-haired Kate Middleton to finally take the plunge.
