Huge crowds turned up to see Jonnie in action, with videos shared to social media capturing their smiling faces as Jonnie spoke on stage about how ‘lovely’ it was to be there.
Taking to his own Instagram after the event, Jonnie shared a sweet photo of himself alongside Jasmine.The Escape to the Country star put an arm around his colleague, who wore a floral purple frock, and smiled for the camera.His caption read: ‘Reunited with this beaut for the day. Great show and so nice to meet all the viewers looking to make their dreams come true. Pop over today and see @laurahamiltontv with loads of seminars and great information.
