Jamie Foxx has shot down rumors he’s dating Katie Holmes as “100 percent not true,” and was spotted in full party mode this week. The “Annie” actor was at Finale’s Tuesday.Baby.Tuesday bash, and gave an impromptu performance.

“He was singing from his table, going back and forth on a mike with DJ Reach, before making his way inside the DJ booth,” explained a spy.

Foxx rapped along to tunes by Jay Z, Kanye West, Drake and French Montana — and a nearby table sent him 20 bottles of Cristal.
