The Project brutally roasted as they suffer an epic social media fail and mix up two iconic stars

The Project was brutally roasted on Monday after the show made a shocking social media blunder.

Channel Ten’s Facebook posted photos of its celebrity guests this week, which include Cate Blanchett and Dolly Parton.

One was a picture Blanchett, 54, to confirm she was Tuesday night’s guest star while another was of Parton, 73, who is appearing on the program on Wednesday.

However the name text for Parton’s photo was not amended, and they labelled iconic American country music star as ‘Cate Blanchett’.

Fans quickly noticed the error and slammed Channel Ten for the mistake.

‘This show is a joke,’ one wrote as another chimed in: ‘Wow, Cate has really changed her look’.

‘You guys are useless,’ a third person vented. 

Blanchett is currently in Australia to promote her latest film The New Boy while Parton is promoting her upcoming album Rockstar. 

The Aussie actress looked as chic as ever as she attended a screening and Q and A session in Sydney for the movie on Sunday.

She opted for a high fashion ensemble as she posed alongside the film’s director Warwick Thornton and producer Kath Shelper.

The star appeared relaxed as she posed with her crew on the red carpet alongside the media wall.

She was recently spotted in Cannes promoting the drama, where Cate plays a nun with a rebellious streak.

The Oscar winner first rose to prominence with her star-making performance in the 1998 historical drama, Elizabeth.

Cate later won the Best Supporting Actress Oscar in 2005 for her role in The Aviator, opposite Leonardo DiCaprio.
