Golf superstar Brooks Koepka got on one knee and popped the question to his gorgeous GF Jena Sims ... and she said, "YES!!!"
... A MONTH AGO!!!
Of course, 30-year-old Brooks and 32-year-old Jena are known to have a good time and some lighthearted fun -- and their engagement announcement was no exception.
Living up to their steez, the couple decided to wait nearly a month to announce their plans to get hitched on the biggest "Fake News" day of the year -- April Fool's Day.
