Nine star Kate Hudson and Yankee star Alex Rodriguez have reportedly split aftera months-long relationship that saw the actress cheering him on during the World Series.

The two started dating in May.  Hudson, 30, had been seen cheering for A-Rod, 34, at several Yankee games. She was also there to celebrate with him when the Yanks nabbed their 27th World Series title in November.

News of the split comes just days after Hudson answered vaguely to David Letterman's questioning regarding A-Rod during her appearance on his show.

A-Rod, it turns out, spent the weekend in Miami – without Hudson – attending an Armani Exchange party Saturday at the Delano Hotel, where accounts differ on how close he got to one of the female guests. One source says he "flirted with a blonde," while another source says he "may" have flirted, but more likely was "just being friendly."
