Cher blasts Donald Trump's wifeLos Angeles, July 19(AZINS) Veteran singer Cher has slammed US Republican Presidential nominee Donald Trump's wife Melania on Twitter.

Melania Trump appeared to have lifted a chunk of her speech during the opening night of the Republican National Convention from First Lady Michelle Obama's speech at the 2008 Democratic convention on Monday night.

A two-paragraph section of the speech on Monday night in which Melania Trump talks about growing up valuing hard work and passing on those values to her children closely mirrored Michelle Obama's 2008 speech, which was seen as a breakout moment for the future first lady and a humanising moment for her husband, President Barack Obama.

The 70-year-old singer, who has been very vocal about her feelings towards the presidential hopeful in the past, branded Melania a liar, reports express.co.uk.

Cher was one of many saying the 46-year-old copied Michelle's address from her 2008 convention speech, emphasising the importance of hard work.

"Oh, (it) just keeps getting better. Trump's wife said she wrote her speech, but it is the speech Michelle Obama delivered at DNC convention. Oh God," Cher tweeted.

"She said, 'I wrote as much as I could'. The rest she stole from Michelle Obama. She lied. Trump lies enough for any family," she added.
