Twitter was awash with speculation this week after actress Uma Thurman showed off a seriously dramatic transformation on the red carpet.
The star was in New York for the premiere of her new NBC show The Slap, but was barely recognisable as she posed for photographers.
Uma's skin appeared far smoother than usual, and the difference was especially noticeable under her eyes and across her forehead.
While the new look could of course be down to a new hairstyle and a lack of eye make-up, social media soon exploded with speculation about whether Uma may have undergone cosmetic surgery over the past few weeks.
Oh dear what has Uma Thurman done to her face?!

Others were quick to defend the Kill Bill actress' new look:
@CTVNews Uma Thurman stops wearing eye liner, mascara and false lashes, culture freaks out and calls it "surgery". Femininity is just fake.

For reference, here's Uma at at another event, the House of SpeakEasy Gala in New York, just two weeks ago:
This isn't the first time in recent months that an actress has been hit with online criticism for a drastic makeover. Last year, the world's media went into meltdown as Renée Zellweger walked the red carpet with a noticeably different appearance.
Renée never confirmed or denied getting surgery, simply saying, "People don't know me in my forties. Perhaps I look different. Who doesn't as they get older?! Ha. But I am different. I'm happy."
We wonder if Uma's response will be similarly cryptic?!
