At least that's what the NY Post is reporting!

"Derek and Minka are secretly engaged," an insider told Page Six. "The wedding is being planned and will take place after baseball season is over."

Though a rep for the actress denied the reports, Page Six added that the Yankees star and his lady love are telling close pals to "save the date" for nuptials in the fall.

Hmmm, this isn't the first time they've quashed claims about their romance...but are they just trying to be sneaky? It's certainly worked for Tom and Gisele and plenty of other celebs!
