Tonight, Classic FM presenters Myleene Klass and Dan Walker will lead a star-studded line-up for a two-and-a-half hour spectacular at the prestigious west London venue.
The 46-year-old, who is a proud mum of three, couldn't contain her emotion during her appearance on the panel for the ITV show as they spoke about giving birth.
Myleene Klass showed off her effortless street style on Saturday on her way to Smooth Radio. The 48-year-old presenter donned a sheer grey long sleeve shirt, stretched to her thumbs.
