The mother-of-two, who is married to record producer Chris Hughes, wowed in white when she arrived at the London Palladium with Lexi, 13, and Hollie, seven.
The well-dressed trio posed for pictures during the press night for Joseph and the Amazing Technicolor Dreamcoat, which has returned to the West End for a limited run.
Last night saw Jason Donovan, 51, return to the famous Andrew Lloyd Webber musical – this time playing the Pharaoh instead of the lead role – alongside Sheridan Smith, 38, who stars as the narrator and Jac Yarrow, 21, who plays Joseph.
Amanda Holden, who is currently presenting the Heart FM Breakfast Show with Jamie Theakston, wore a beautiful white satin shirt dress from Hasan Hejazi for the occasion, teaming it with a pair of metallic gold heels.
Wearing her hair in a sleek straight style, she enhanced her good looks with glamorous evening make-up and classic red nails.
Her eldest daughter opted for a pretty pink dress which she wore with a matching denim jacket and stylish espadrilles while her youngest child wore a colourful striped dress with gold shoes like her mum.
Following the show, the television and radio personality posed for pictures with the stars of the musical and took to Instagram to share a snap with her 1.2 million followers.
Alongside a photo of Amanda and Sheridan, she wrote: “Absolutely love this talented, incredibly funny girl @sheridansmithster watched her along with the fabulous @jdonofficial and the phenomenal @jacyarrow in @josephmusical tonight!”
She continued: “If you get a chance – go see it with your friends and family over the summer @thelondonpalladium. You’ll love it”.
