Floyd Mayweather's Las Vegas mansion was burglarized over the weekend.

Thieves made off with $150,000 worth of goods including luxury items such as high-end purses and a pricey watch, according to TMZ.

The crime occurred just as the boxer was celebrating his 40th birthday with pals Justin Bieber and Mariah Carey in Los Angeles. 

Mayweather's Sin City home is located in a gated community near a golf course.  

The criminal broke into the mansion through a door in back of the house. It was noted that several items in addition to the purses and watch were taken.

No word yet if there are any suspects. 

Meanwhile, the star was having the time of his life in Los Angeles.

Mariah looked lovely in a gold gown as she sang a song for the knockout king. And even Bieber - a longtime friend - got up on stage. 

Floyd was presented with a multi-tiered birthday cake. 

TMT (The Money Team) featured as the top level, with boxing gloves, a championship belt and suitcase full of cash completing the iced decorations.
