The pair are firm friends and their friendship was described as a 'bromance' by Sky Sports on Saturday.
The Fulham versus QPR clash was Sky Sports' live EFL offering at the weekend and it did not disappoint, with the Hoops coming back from 2-0 down to draw 2-2 at Craven Cottage.
Sky interviewed the pair ahead of the game, and it was shown prior to kick-off.
And Smith, who spent two-and-a-half years at Fulham before joining QPR in January last year, had high praise for his mate Cairney.
The QPR frontman said: "Once he's fully fit I don't think there's a better player in the division and Fulham are probably the best footballing side in the division."
