The Princess of Wales brushed off a lone protestor as she joined rapper Professor Green for a poignant visit.
She went to the Foundling Museum in Central London this morning to meet foster parents and people who have experienced the care system.
Kate is patron of the museum which tells the history of the Foundling Hospital, which in the mid-18th century began caring for children abandoned by their mothers who could not look after them.
Arriving at the venue, the princess wore a smart Alexander McQueen trouser suit in a fun pink shade that she teamed with a pearl-style belt.
When she first turned up a lone protester held up a placard as her car passed but the was kept some distance back by a police officer as she stepped from the car.
Kate seemed unfazed by the person and focused on meeting representatives from the museum who stood outside the building to greet her.
Inside, she was joined by Professor Green as she met young people who have been in care and have taken part in the museum’s Tracing Our Tales programme.
The initiative aims to give them the skills and confidence to deliver learning programmes at the museum, return to education, secure apprenticeships and jobs, alongside the ability to express themselves creatively
Kate also spent time with adoptive parents and foster carers to discuss the lifelong impact that positive, supportive relationships can have on children and young people.
Afterwards, she headed to the Kinship charity where she met kinship carers - people who raise the children of close friends or relatives.
There, Kate sat on a playmat and passed toys to children as she discussed the important role kinship carers play in a child’s development, the challenges they face and the support available to them provided by charities such as Kinship.
She was also introduced to Professor Green's grandmother Nanny Pat - who had even bought a new blouse for the occasion.
The songwriter’s grandmother got up extra early to have her hair done on Thursday before being introduced to Kate at the support group session in Camden.
Professor Green, born Stephen Manderson, was raised by his grandmother after his mother gave birth to him at the age of 16.
He said his Nanny Pat was "very nervous" to be meeting the princess and had got her hair done beforehand and bought a new blouse.
The rapper added: "It’s the first time Nanny Pat met Kate, she was very nervous.
"My aunty had her up early to do her hair and bought a new blouse. She was very excited."
The singer said his "kinship experience" began when a nurse handed him to his grandmother as a baby in hospital instead of his mother.
He added: "The nurse handed the baby to my nan as she looked more the age."
Speaking about being brought up by his grandmother, Manderson said: “It was just the done thing. Family doesn’t necessarily mean two parents with 2.4 children. My home wasn’t broken.
“The amazing thing about charities like this is it’s focusing on early intervention, there’s things as a child I would’ve better coped with.”
The trip to the museum and charity is Kate's second outing this week after she made an unannounced visit to the Chelsea Flower Show on Monday.
There she joined pupils from schools taking part in the show's first children's picnic.
