Vince Vaughn is crashing a famous club ...

because he just got his star on the Hollywood Walk of Fame. The "Wedding Crashers" star received the honor Monday ..

. soaking it all in alongside his family ..

. and Mel Gibson !!! As you can see, Vince is looking dapper with a two-piece suit ..

. and Mel is much more relaxed and casual. But hey, it's Vince's big moment, not Mel's.

Vince used his speech to thank a bunch of people who helped him get to this point ...

namely, his wife Kyla Weber and their two kiddos ...

daughter Locklyn and son Vernon . VV even gave his "beautiful wife" a kiss during the ceremony. No smooches for Mel.

The Hollywood Walk of Fame star is certainly well deserved ...

Vince has played big roles in a ton of hit movies since getting his big break way back in 1996 in "Swingers." We're talking classic comedies like "Old School," "Starsky & Hutch," "Anchorman: The Legend of Ron Burgundy," "Dodgeball: A True Underdog Story," and on and on. Congrats, Vince!!!.
