Baseball star Alex Rodriguez has reportedly splashed out on a $40,000 ring for girlfriend Kate Hudson to thank her for cheering him on through the World Series. Rodriguez's team, the New York Yankees, triumphed in the series against the Philadelphia Phillies to become the the 2009 World Champions - and Hudson was at the games to show her support.

She often showed up with her mother Goldie Hawn's actor lover Kurt Russell.

And A-Rod has shown his gratitude by buying his girl a new Louis Vuitton white-gold ring set with pink sapphires and diamonds.

An insider tells In Touch magazine, "He has a World Series ring, and now she does, too. It’s a beautiful piece of jewelry and very unusual... He clearly knows her style and has great taste... She thought it was such a romantic gesture."
