Myleene Klass was working petal power this weekend at the Big IF event in Hyde Park, looking super-pretty in her blue floral-print strapless frock.
Earlier on in the day, she'd also wowed in a white sundress at the rally encouraging world leaders to act on the issue of global hunger.
But, while she was looking flawless, there was a momentary panic when the singer turned entrepreneur's dress strap broke - and she had to put it back together with a safety pin.
Very Pretty Woman.
Despite the mishap, she was ever the professional, and still oh-so-chic.
