Scherzinger, 36, and formula one racer Hamilton decided to end their five-year on-off relationship last month as the couple did not have enough time to spend together, reported Contactmusic.
"I am trying to be there for her because it is a tough time. It isn't easy to switch off after spending five years in a relationship. I think it was just obvious that the distance thing might have taken its toll," Douglas said.
"But she's a strong woman and she's not silly. She is very into her faith, so she knows how to get through something and just needs the right friends around her," he added. The 'Boomerang' hitmaker is believed to be emotionally moved when Hamilton dedicated his victory in the Hungarian Grand Prix.
