Russell Brand has given $630 to a homeless man.

The 36-year-old Arthur star reportedly saw the man was down on his luck and decided to help him out.

"Russ decided to do something charitable. He met a homeless guy on Hollywood Boulevard, just around the corner from the home he shared with Katy Perry. Russ was with his new girlfriend and they struck up a conversation with the guy. After chatting for a few minutes he decided he wanted to get him a roof over his head for a few nights. So he went over the road and withdrew $630 for him. When Russell handed over the wad of cash, the fella had tears in his eyes. Russ told him to spend it wisely and to make sure he says 'Hello' if they ever cross paths again," a source told The Daily Star.

Meanwhile, the comedian has introduced mum Barbara to new girlfriend, model Nikolett Barabas. The trio were spotted helping Russell house hunt in Los Angeles over the weekend following his arrest for allegedly throwing a paparazzo's iPhone through a window last week.
