The '5 Minutes' rapper met the famous couple at the BAFTAs and described them as ''very beautiful'', insisting they made me realise it is possible to be a star ''without become a real a-hole''.
Speaking to the Mail on Sunday newspaper's Event magazine, he said: ''I met Brad Pitt and Angelina Jolie at the BAFTAs.
''They're both very beautiful people, in every sense - the aesthetics are amazing - but I always looked for humility in these kinda stars and they really are humble people.
''They offer you hope that you can reach the heights of stardom without becoming a real a-hole.''
However, Tinie was less than impressed with Gary Barlow, insisting despite his talent ''as a songwriter'' he has lost respect for the Take That star after it emerged he'd been caught up in a tax avoidance scheme.
He insisted: ''That tax thing is a bit annoying. Actually, it makes me angry because I pay my taxes.
''Apparently there are people fighting Barlow's corner saying, 'Let him keep the money'.
''Like, really? I respect him as a songwriter but not as a taxpayer.''
