Spice Girls legend Mel B wowed fans on Monday as she posed on the red carpet at the launch of the new series of America’s Got Talent.

The 42-year-old singer and TV judge looked decades younger as she posed with her 19-year-old daughter, Phoenix.

Many fans took to social media to comment how Mel and Phoenix could pass for sisters rather than mother and daughter, with many praising Mel for looking "incredible".

But, inevitably, some trolls opted to mock Mel and question if she had employed some cosmetic help to keep herself looking young.

Fans on Twitter and Instagram noted that Mel’s cheeks looked a little puffy - with some questioning if she had experimented with fillers.

“Has she had surgery or is it the make up?” one fan asked on social media, although many others were convinced she had.

“She’s had fillers. It can take around 4 weeks for the swelling to go down,” one convinced fan wrote.

"I reckon she's had surgery her eyes look different,” commented another.

While a further fan suggested Mel was beginning to morph into a rival pop star, writing: "she looked like Mutya Buena now."

However Mel herself gave fans an insight into her rigorous beauty regime as she shared a photo on Instagram on Sunday.

The image showed the star working on a laptop while lying on a bed as a team of beauty experts got to work on her face and body.

“This is how we do hair make up and mani pedi all at once boom!” the star wrote as she showed herself simultaneously getting an "all over custom body spray tan."

Fans had been left impressed when she shared the image on social media at the weekend, with one writing: "No wonder you look so good."
