Pamela Anderson is totally hooking up with Chuck Zito now that she's single ... is what you'd think looking at this picture.
Anderson and Zito were heading out of the Rainbow Room Friday night ... and shortly after, the duo was pictured face to face in Pam's ride.
As we previously reported, Anderson filed for divorce from poker player/"One Night in Paris" star Rick Solomon this week -- their second time splitting up.
At first glance Pam appears to be macking down on her ex-boyfriend -- they briefly dated in '07 -- turns out one of our camera guys shot them on video as well ... and they're clearly hugging.
Nothing to see here folks ... yet.
