A bob and a brunette: Amanda Seyfried and Jennifer Lopez are hair chameleons.

The Tony Awards last night were filled with stellar performances, red carpet glamour and of course plenty of jazz hands, but it was two celebrity hair transformations that really stole the show (excuse the terrible pun).

After chopping off most of her hair into a lob last week, Jennifer Lopez has proven just what a versatile haircut it is.

J-Lo first debuted her voluminous wavy bob on the set of her new TV series Shades of Blue.

The singer has been well-known and admired for her killer haircuts and styles over the years, but it's refreshing to see the 45 year-old ditch the extensions and rock a more natural look.

And how about that delicious honey blonde-brunette colour?

But it doesn't stop there. Proving there's no such thing as a bad hair day for Lopez, she turned heads again at the Tony's with a sophisticated 'do. A sweeping side fringe paired with classic Hollywood waves showed off her new cropped length... and it's easy versatility.

Amanda Seyfried

Could Amanda Seyfried's hair be the latest mind-boggling equivalent of 'The Dress'?

Known for her Rapunzel-esque flowing blonde locks, it was big news when the actress stepped out on the red carpet with what looked to be much darker brunette hair slicked back into sleek bun.

But now The Glow office is divided.

Paired with her black and golden dress and deep brown smokey eye, Seyfried's hair looks a long way from her signature golden blonde. In fact, it appears to be the same colour as her (definitely) brown eyebrows.

Yet is it just a trick of the light? (Post continues after gallery.)

While the majority of photos from the evening appear to show the 29 year old with darker hair, there are a few with slightly different angles and lighting that are enough to make us second guess what we're seeing. Like this one.

So, is it blonde or brunette? While we can't quite decide on the colour, we can say with 100 per cent certainty that Seyfried looks delightful either way.
