The future of Ugly Betty remains uncertain after the hit comedy show received a slump in ratings, according to the latest report.

The television show - which has welcomed guest spots from Naomi Campbell, Lindsay Lohan and Victoria Beckham - has lost its popular Thursday night slot on U.S. television to Samantha Who.

An ABC spokeswoman tells The Sun: “The Thursday night block is a good opportunity to launch these comedies.

“That said, Ugly Betty is a solid performer and there is no question that it will definitely be back to complete its season — just without repeats.”

Industry experts have also revealed that the show's air time could face being moved from Spring to June, alongside repeats and gameshows.

The same worrying drop in figures has also emerged in the U.K, but Channel 4 bosses are eager to keep the show running on their schedule.

A C4 insider said: “We’re looking forward to having Betty back.”
