By late 2008, fans were eager to link the stars off-screen as well as on. But Kristen was in the midst of a long-term relationship with "Sky High" actor Michael Angarano, who accompanied her to the 2008 MTV Video Music Awards in September. And Rob seemed to be enjoying the single life just fine. The actor was spotted out and about with a series of beauties, but denied he was in the market for a serious relationship. "I'm not like prowling around, no!" he said. One of Rob's alleged paramours was none other than "Twilight" co-star Nikki Reed. "They were hooking up, but it wasn't anything serious," a source said of the fling. Nikki eventually called things off when she realized Rob had a thing for Kristen, her best friend at the time.
