Wahlberg to Mayweather -- You're a Great Boxer, But that Jewelry ... Fabulous! (PHOTO)

Mark Wahlberg was blown away at the Clippers game last night, but it had nothing to do with the Clippers rout over the Rockets ... he was mesmerized by Floyd Mayweather's bling.

Mark and Floyd were sitting courtside, not beside each other, when Mark walked over to Floyd to admire his ridiculously expensive bracelet.

Meanwhile, Khloe and Kendall had laser focus on the game ... at least for a second or two.

Tons of stars showed, including Billy Chrystal, Macy Gray, Adam Devine and Bob Odenkirk.
