Hot mama! Blake Lively’s sleek new hairstyle is impossibly glamorous –

Did Blake Lively just get her most dramatic haircut ever?

The actress, 30, sported a gorgeous, shoulder-length bob at a recent screening of her new drama, “All I See Is You.”

She exuded classic Hollywood glamour with the flirty lob, pairing it with a figure-flattering white blazer, slit skirt and sparkly pumps, rounding off the look with a sultry red lip. (We think she’s channeling Hollywood legend Lauren Bacall!)

We’re obsessed with her short ‘do, but the jury is still out as to whether it’s permanent: It looks like she may have pinned her long locks up for the night.

Getting such a drastic chop would certainly be a major hair transformation for Lively, who is known for her long, flowing blond strands.

See her past hair looks:

She briefly tried out life as a redhead, sporting flowing, mermaid-inspired waves at the Time 100 Gala in 2011.

By 2014, the actress had found her signature hairstyle — long waves with plenty of body and subtle highlights.

Last Valentine’s Day, Lively got creative and wove her hair into a heart for a L’Oreal event.

Then, of course, there are all the times she made a simple ponytail look impossibly glamorous.

We’re not sure if her latest, shorter look is here to stay, but we do know she will always give us serious hair inspiration!
