And if ever there was a bizarre Hollywood hair trick to see in the making, hers was it...
Eva looked sizzlingly sexy at this weekend's 22nd Screen Actors Guild Awards, which were held at The Shrine Auditorium in Los Angeles and saw the likes of Kate Winslet, Claire Danes, Brie Larson and Kaley Cuoco looking stunning on the red carpet.
Wearing a khaki green, see-through Julien Macdonald dress, she clearly wasn't fussed about wearing undies for the occasion.
And why should she be? With a figure like Eva's, we'd probably be happy to tread the red carpet in swimwear!
Like many of her fellow A-list attendees, Eva also showed off some of her pre-awards secrets as she took to the make-up chair in the run up to the event.
But while we all have some interested beauty tricks up our sleeves (washing just our fringes and only painting the toenails you can see being just two of them), we've NEVER seen playing cards used as beauty tools before...
"Playing (cards) with my girl @evalongoria getting ready for the #SagAwards," top celebrity hairdresser Ken Paves Instagrammed, along with some behind-the-scenes snaps.
What the heck is going on?
Well, Eva wore a slight soft wave in her slick hair, which was a big trend on the night. But her roots were left pretty straight which she clearly didn't want to ruin while she had her make-up applied.
So, in order to protect her hair, she turned to a bunch of diamonds, hearts, clubs and spades!
Pretty clever when you think about it – after all, no-one wants to see clip marks in their hair after they've had their make-up done.
We salute you, Eva. And can we get your hair and make-up team on speed dial, please?
