While at the shopping centre, Amanda donned tennis whites and recreated the famous ‘Tennis Girl’ poster from Athena’s 1977 calendar.
However, unlike the original model, Amanda decided to keep her pants on, and sported tiny white shorts under her dress.
The TV star was joined by Tim Henman and Andy Murray’s mum Judy. The trio played a few games of tennis at the Robinsons Pop-Up And Play court, where Amanda took the chance to get some expert tips from Tim and Judy.
“With Judy’s help I’m hoping I now have the skills to beat my husband!” she said.
Amanda has had a busy two weeks on ‘BGT’, joining her fellow judges on the final for last week’s live semi-finals and last night’s grand final, which saw musical theatre band Collabro scoop first place.
