Blake Lively is unrecognisable on the set of 'The Rhythm Section'

Blake Lively has been hard to recognise over the last three months.

The 30-year-old actress, who is currently filming The Rhythm Section, has been photographed showcasing a number of different looks.

The Mark Burnell book series adaptation sees Lively play a woman who investigates her family’s deaths in a plane crash by assuming different identities.

The role has seen her adopt a multitude of on-set looks, including this one.

Snapped on Saturday, the former Gossip Girl star could be seen with glamorous pin-up girl bangs, bright red lips, and wearing a long black coat.

Lively, who co-stars alongside Jude Law in the upcoming flick, was also spotted sporting a Kris-Jenner style hairdo last month, with an all-black outfit and minimal makeup

And on November 8, Lively’s husband Ryan Reynolds expertly trolled her with another The Rhythm Section photo.

The mother to daughters Ines, 1, and James, 2, wore a shorter, brassy blonde cut, but covered her with a blue beanie while wearing unflattering, over-sized clothes, and no makeup.

Reynolds shared the photo of his wife to Instagram, with the cheeky hashtag “#NoFilter”.

"Only the best for SMA 2010," she responded, in reference to Reynolds being named People's Sexiest Man Alive in 2010.

Brilliant.
