The 'Noah' star is reluctant to strike up a romance with someone because he doesn't think it's fair Charles, 10, and Tennyson, seven, whom he shares with ex-wife Danielle Spencer, have his love-life flaunted on their faces, reported Contactmusic.
"I have the responsibility of my two boys and I don't want them thinking anything other than their mum is the most perfect woman in the world.
