Katie Holmes Did Party with Jamie Foxx at His 50th Birthday Bash

EXCLUSIVE

Jamie Foxx was NOT flying solo at his huge 50th birthday event — Katie Holmes was by his side and we’ve got the video of them flirting like a couple of teenagers.

Katie got onstage with her man Wednesday night at Paramount Studios — and at least for these few moments … couldn’t keep their hands off each other. The couple’s been together for 4 years, but we’ve only seen PDA shots once before. Normally, they avoid all public photos or video.

As we reported … Jamie went old-school with the playlist … with Ice Cube, Snoop Dogg, Ludacris and Too Short.
