The former Desperate Housewives star shared a picture of her new fiancée with her 1.9 million Instagram followers shortly after he got down on one knee.
The proposal took place in Dubai, where the couple were attending the Global Gift Gala at the 2015 International Film Festival.
The social media snap showed Eva and Jose kissing in the desert, surrounded by sand dunes, with the actress wearing an impressive diamond and ruby rock on her finger.
Eva captioned the picture; 'Ummmm so this happened... #Engaged #Dubai #Happiness'
The Texas-born star shared the build-up to the proposal on her Snapchat, revealing the romantic setting complete with red velvet sofas scattered with rose petals, a picnic and champagne.
Later on in the day the couple made it even more memorable by riding camels back to their hotel.
Jose is a television executive, President of Televisa, and businessman, and has been dating the 40 year old actress since 2013.
Now we are waiting to see a congratulatory message from best friend and fellow celebrity Victoria Beckham! The pair have been close friends ever since the British family moved to Los Angeles in 2007.
But Eva is clearly smitten with her new man, as she posted a picture of Jose in a tuxedo, captioned; 'No words for this handsomeness!'
Having been known to wear her heart on her sleeve, Eva and Jose made their public debut at a dinner in Mexico City only a few weeks after they started dating.
This will be Eva's third marriage. Her first was to fellow actor Tyler Christopher, from 2002 to 2004, and second to American basketball star Tony Parker from 2007 to 2011.
Her marriage to the sports star ended after Eva found 'hundreds' of text messages from other women on his phone.
We're keeping our fingers crossed that it's third time lucky for Eva!
