Eva Longoria just got an early Christmas gift -- a red ruby engagement ring from boyfriend Jose Antonio Baston!

Apparently the couple became betrothed in Dubai, where the Desperate Housewives star, 40, and her businessman boyfriend, 46, are attending the Global Gift Foundation event. The actress captioned the photo, "Ummmm so this happened. #Engaged #Dubai #Happiness"

The pair started dating in November 2013. Baston is the president of Televisa, Latin America's largest media company and the world's largest Spanish-language media conglomerate. Oh ... and did we mention ... he's HOT! Congrats to the beautiful couple!
