Lakers' Jordan Clarkson -- PDA with Chanel Iman ... Victoria's Secret Model

Might be a hot new couple in Hollywood ... 'cause last night Lakers stud Jordan Clarkson hit the clubs with Victoria's Secret model Chanel Iman -- and TMZ Sports has a shot of the two of them holding hands on the way out!

The 22-year-old NBA rising star was leaving DBA nightclub holding hands with the supermodel ... who has been featured in everything from Sports Illustrated to Vogue.

No word on how serious they are ... or if they're even an official couple ... but our sources who were there say last night, it sure seemed like there was some chemistry between the two.

BTW, this wouldn't be Chanel's first celebrity relationship -- she was engaged to rapper ASAP Rocky ... but they broke things off back in 2014.
