Joakim Noah's model girlfriend Lais Ribeiro was so damn hot in her thong bikini in Malibu this weekend -- we barely noticed the beach was littered with a ton of HUGE stars!!
Seriously ... everyone from John McEnroe to Kenny Chesney and Cindy Crawford and Rande Gerber were hanging out at Laird Hamilton's pad for a Sunday funday.
But, all eyes were on Joakim and Lais ... for obvious reasons.
Joakim was waived by the Knicks last month -- and while they lost to the Washington Wizards that day, Noah was having a much better time.
