Jennifer Hudson and Common have a strong bond between them ... they were holding hands and joined at the hip sitting courtside at a Lakers game.

The couple strolled hand in hand into Crypto Arena for Wednesday's matchup against the Dallas Mavericks, plopping down in their seats for a front-row experience ... and looking pretty fashionable.

J-Hud and Common's date night is proof they're still going strong as a pair ... they were smiling and chatting, and Jennifer even introduced Common to another couple sitting beside her.

LeBron James and the Lakers won in a blowout, 127-110, and Jennifer and Common hit the exits together before the final buzzer ... saying goodbye to some folks on their way out.

Jennifer and Common have been together for a while now, and this outing means they're showing no signs of slowing down. He's said they might make a record together eventually, but it's got to happen organically.

Check out the video ... they make a pretty cute couple!!!
