Could Alexander Skarsgard soon be back on the market? Hold on to your libidos, people, because Us Weekly claims Kate Bosworth, who began dating the strapping "True Blood" star about a year ago, recently got reacquainted with the lips of an old pal during a family visit to Massachusetts. "Kate made out with her high school boyfriend," alleges a source, who believes that the wispy starlet was "feeling down" about news that her former flame Orlando Bloom was expecting a baby with newly minted missus Miranda Kerr. "Her high school ex is comfortable," says the snitch. "And he's still smitten with her." But a rep for Kate, who didn't accompany her Swedish squeeze to Sunday's Emmy festivities, dismisses the rumors, telling the mag, "This is untrue. She is good friends with her high school boyfriend."
