Looking far younger than her 47-years, Amanda looked perfect in her one-sleeved midi dress as she made her way into the Lowry Theatre alongside Alesha Dixon, David Walliams and hosts Ant and Dec.
The Alex Perry number – which costs £1,232 – also featured a dramatic, caped full-length sleeve that hung down to her knees and highlighted her gym-honed arms.
Amanda finished off her eye-catching look with a pair of white pointy heels, beach-wave hair and a classic smokey eye.
Meanwhile, Amanda last made headlines earlier this month when she it back at trolls who criticised her for kissing her daughter, Hollie on the lips.
Posting the image from her family holiday in Bahrain, the 47-year-old was shocked to find that what should have been seen as sweet moment of mother-daughter bonding, caused a furore among her 945,000 Instagram followers.
One user wrote, “Standby for trolls saying kissing on lips is perverted or some crap!”
To which the TV presenter and actress replied, “@andrew.bell.7121 b**locks to them. #family. They’re not well x”
Another questioned what outspoken Good Morning Britain host Piers Morgan would make of the image, writing, “What would @thepiersmorgansay?”
Amanda offered up a succinct reply making a subtle dig at Piers’ well-publicised disdain of Bond actor Daniel Craig wearing a papoose to carry his baby daughter Ella. She wrote, “@j.dagnall well there’s no papoose so we should be ok!”
However, most rushed to reassure the mum-of-two, telling her to ignore the naysayers.
One wrote, “@noholdenback I still get kisses from my 16 yr old twin boys even at school drop off I know bloody miracle! Long may it continue.”
While another agreed with Amanda’s earlier sentiments, adding, “@noholdenback absolutely! Only someone with something wrong would ever see wrong in kissing your child. Most natural thing in the world.”
