Jamie Foxx and Katie Holmes Tight and Together at Clive Davis Pre-Grammy Party

Jamie Foxx and Katie Holmes were not hiding Saturday night ... staying close to each other and circulating among the celebs at Clive Davis' annual pre-Grammy party.

Clive's been hosting bash every year since 1976, and this year didn't disappoint.  As we've already shown you, Jay Z, Beyonce, and a slew of other celebs hit up the Sheraton in New York City.

We're told Jamie and Katie had a few drinks and were super tight the whole night.  As you know, they've been together for years now but with a few exceptions they've kept things on the QT ... not anymore.
