Russell Wilson -- Cruisin' With Samantha Hoopes ... Is He Dating Bikini Model?!

Here's video of Seattle Seahawks quarterback Russell Wilson out in Hollywood ... with Sports Illustrated Swimsuit model Samantha Hoopes riding shotgun -- so, is this a date?!??

The two were leaving Katsuya in Hollywood in what appears to be a pimped out vintage Rolls-Royce convertible ... with some dude sitting in the backseat.

Wilson is very single after pulling the plug on his two year marriage to his college sweetheart Ashton Wilson last year.

As for Hoopes ... she's 24-years-old and smokin' hot ... and also loves football.

We're trying to find out more ... in the meantime, enjoy these photos ...

9:40 AM PT -- Well placed sources tell us ... the two are definitely NOT in a relationship ... but really enjoy hanging out with each other.
