The model and former First Dates star was in the city for a personal appearance at Halo nightclub but stopped to offer assistance, according to a Twitter user.
A woman named Emily Douglas tweeted today: "Thanks to @SamReece for giving me money to give to the sweetest homeless man last night hope you liked Bournemouth."
Sam replied: "My pleasure."
The 23-year-old had earlier tweeted: "Looking forward to partying at @halobournemouth tonight. Heard so much about this place, never been as excited to go to church."
He's been in the headlines over the past month thanks to now ex-girlfriend Stephanie Davis. She entered Celebrity Big Brother all loved up with Sam and declaring she was going to marry him, but ended up falling for housemate Jeremy McConnell.
She said last week: "I think when the trust is gone, it's gone, that's it. And now it's about putting myself first rather than always giving 100 per cent to everyone else. I think Sam would understand because I think he knows he loves me so much that he broke my heart. I think he would look at me and think, I know I lost you a long time ago. It turned toxic. He was holding on to something I ended up losing the love for."
Sam has yet to give any interviews on Stephanie or Jeremy, or really say anything about the situation other than to deny "hurtful" accusations he'd cheated on Stephanie and insist he hasn't been "cashing in" on what's happened.
