Watch: The Block's Ling and Zing show off their singing skills

The boys had everyone in stitches with their songwriting talents on last night's episode.

The Block NZ's DIY duos took some time out from their renovation responsibilities this week to participate in the annual 'Block Stars' talent competition, which pits each team against each other in the ultimate performance battle.
Brothers-in-law Andy and Nate donned pink tutus for their set, Julia and Ali suited up in sumo wrestler costumes, and Stace and Yanita pulled off a magic show enlisting the help of Stace's two boys, all to the delight of the assembled crowds.
It was Ling and Zing, however, who seemed to bring the house down with their hilarious song carefully written about their time (and fellow contestants) at Block HQ.
Check out their performance in the video above, and catch the full thing here.
