Jeanie Buss is usually rocking power suits in business meetings, but over the weekend — she was decked out in all white on the beach … this after getting married, TMZ has learned.

Sources with direct knowledge tell us the Lakers owner got hitched to comedian Jay Mohr Sunday during a small, intimate ceremony in Malibu — where about 20 close friends and family members in attendance … and the bride and groom looking happy as can be.

As you can see in this photo, Jay was over the moon when Jeanie said “I do” … sweeping her off her feet and holding his bride up with a gorgeous backdrop behind them. BTW, our sources say there weren’t any famous people in attendance … meaning no players.

That’s reflected in the vibe here — super casualchill, but Jeanie looks great in her gown — which is quite traditional. It’s a great ending for a couple who’s been together for years now.

While she first went public with their relationship just in 2021 … we know she and Jay had quietly started dating as early as 2017 — this after she broke it off with one-time fiancé Phil Jackson in 2016. Since then, Jeanie and Jay have been inseparable — and very in love.

They announced their engagement in December 2022 … and now 9 months later, they’re man and wife.
