A father pushed his son to safety when an elderly driver lost control of his car - but then watched helplessly as his wife was killed.
Desreen Brooks, 33, had bent down to speak to their son when the car mounted the pavement and struck her and 23-year-old American student Amy Werner.
Desreen and her husband Ben Dutton, 33, and their two-year-old son Jackson had just left their friends' home in West Hampstead, London, when the crash happened.
Friend Zac Schwarz said: "I still can't quite believe it happened. Ben managed to push his son out of the way and jumped out the way himself so they were fine, but Desreen wasn't."
Heartbroken Ben described his fashion agent wife as 'the most lovely person you could know'.
He said: "We had the most lovely day together. We spent it in an art cafe laughing and joking because Jackson kept trying to paint her mugs and things.
"We left Zac's house and were struggling to get Jackson into his pushchair, as usual. He is a feisty boy.
"She had bent down to say to him that he had been such a good, well-behaved boy all day and that she was so proud of him and those were the last words she said.
"She wore her heart on her sleeve, the most lovely person you could know.
"To be honest what I have drawn from it is what an amazing time we had together.
"We had had an incredible few weeks. We went to the Olympics to celebrate our first wedding anniversary, we had had Jackson's second birthday. Her new business was going really well. It was all going so well."
The couple, from East Dulwich, married in August last year after meeting while waiting in the queue at a nightclub eight years ago.
Neighbours today told of chaotic scenes as the speeding car careered off the road, smashing part of a brick wall and pushing over a set of traffic lights on Saturday night.
The other victim Ms Werner, who was on a postgraduate bursary course student at the University of Westminster, was rushed to hospital and is critically ill in hospital.
The car's driver, an 83-year-old man, was taken to hospital with minor injuries.
Police are examining his car and say there have not been any arrests.
They have appealed for witnesses to call them on 0208 842 1817.
