It looked like Alex Rodriguez rebounded with 25-year-old design consultant Elaine Spottswood awfully quickly after his split with Kate Hudson — and it turns out that may be because the Yankee slugger already had the younger blonde on deck. “Elaine and Alex have been romantic for a few months, since before he and Kate ended their relationship,” says an insider close to the couple, who met through friends a few years ago, but began heating up in November. And apparently, A-Rod didn’t do much to hide his affections: According to one insider, he constantly texted Elaine, even while he was with Kate. In fact, as millions of viewers watched Kate and her family cheer Alex on during the World Series, he was secretly planning sexy dates with Elaine. “Kate is devastated and feels stupid,” says a friend of the actress. “She thought that she and Alex were moving toward marriage, and all the while he was not taking the relationship as seriously as she was. She never would have imagined he would cheat on her.” Elaine openly admits she and Alex are spending time with each other, but insists she’s not behind the breakup, calling it a mutual decision between the two. “It’s only recently that we’ve reconnected, about a month or so ago,” Elaine tells In Touch.
