Host David Walliams' gag about former Love Island presenter Caroline Flack left the audience at the National Television Awards unimpressed at Tuesday night's ceremony.

The star-studded crowd let out a loud boo when the comedian and author joked about Flack being the Masked Singer's anonymous Hedgehog. 

Flack did not attend the awards 

Britain's Got Talent star Walliams, who won Best TV Judge, was on hosting duties at the NTAs for the first time after taking over from Dermot O'Leary.

The Masked Singer's host Joel Dommett and the show's anonymous Hedgehog character joined Walliams on stage to present the best serial drama prize to Emmerdale, which won the gong for a fourth year.

However, when Walliams returned to the stage, he quipped: "Thank you - and so nice to see Caroline Flack back on TV as well."

Flack, who stepped down from the ITV2 dating show Love Island following an assault charge, did not attend the event but wished the cast and crew of the dating show good luck ahead of the ceremony.

The NTAs also saw Ant and Dec win the award for Best Television Presenters for a 19th time, and This Morning earn the live magazine show gong.
