Was Alex Rodriguez just a boy of summer?
The Internet is a teeming with reports that the Yankees star and Kate Hudson have split after a months-long relationship that saw the actress cheering him on during the World Series.
There had been no signs of trouble, and as recently as Friday, Hudson, 30, was a giggly mess when David Letterman pressed her about Rodriguez, 34, during her Late Show appearance.
So what, if anything, changed?
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.”
