Alex Rodriguez may have won the World Series, but Kate Hudson took home the prize!

Days after A-Rod, 34, and his New York Yankees became champions, he gave Kate a $39,000 white-gold ring set with pink sapphires and diamonds from Louis Vuitton. The Les Luxuriantes ring from the French design house was Alex’s way of thanking Kate, 30, for her support during the series, according to an insider.

“He has a World Series ring, and now she does, too,” the insider explains. “It’s a beautiful piece of jewelry and very unusual — just like Kate herself. He clearly knows her style and has great taste.”

The insider says it definitely wasn’t an engagement ring, but Kate was still thrilled nevertheless: “She, of course, thought it was such a romantic gesture.”
