Adam Levine won $10,000 in Las Vegas, then donated it to his assistant's sister.

The Maroon 5 rocker decided it was time to have a blowout with his friends recently, so arranged for him and five pals to jet to the US party city for some fun.

While there, Adam got lucky at dice game craps, managing to pick up $10,000. Rather than pocketing the money to help pay for the vacation, the kind-hearted star immediately turned to his assistant and told him to take the cash.

"I want this money to go to your little sister's college fund," he said, according to National Enquirer.

Adam's assistant was overcome with emotion and leapt into the musician's arms for a huge hug.

The singer's generous gesture comes after he admitted he enjoys playing up to the rock star ideal. He doesn't understand musicians who pretend to live everyday lives to connect with their fans and is proud he no longer has to complete chores.

“[This] was burned into my skull: 'Must make money so I don't have to do my chores, because I wouldn't do them anyway,'” he previously laughed. "It's sweet that I don't have to do my laundry."
