Fueling more rumors of a split, Jake Gyllenhaal showed up dateless for the second time to present two awards at Spike TV’s Video Game Awards in LA on December 12. “He looked tired and expressionless,” an onlooker tells In Touch. “He stayed in his trailer for most of the night.” Earlier during the week, Jake arrived solo to support his sister Maggie at the LA premiere of Crazy Heart, where he stayed close to his family. Amid all the rumors, Jake did recently refer to Reese Witherspoon as his girlfriend during a press conference for his new film Brothers. Although both their reps have denied their split, the couple have not been spotted together since September. Reese, 33, met Jake, 28, while filming Rendition, and the pair confirmed their relationship in summer. "He's fabulous. He really is a fantastic guy." the actress said in the April 2009 issue of Elle. Reese separated from actor Ryan Phillippe in 2007, and they have two children together, Ava, 10, and Deacon, 6.
