Prince Harry has joined Michelle Obama in honouring America's military mothers as he began his tour of the US today.
The Prince visited the White House for a reception with the First Lady and children who were making presents for their mothers.
With Mother's Day traditionally held on the second Sunday of May in the US, around 50 children were busy making presents in President Barack Obama's Washington residence ahead of the weekend's celebrations.
Harry and Mrs Obama watched as around 50 children created goody bags for their mums filled with bouquets of roses, edible salted dough jewellery and baked crisps - but the Prince soon joined in.
He was a surprise guest whose attendance had been kept secret from the 170 invited mothers, grandmothers and children.
It is the first time Harry has returned to America since he was famously photographed naked during a trip to Las Vegas last year.
During his seven-day tour the Prince will attend the Warrior Games - a Paralympic-style sporting championship for injured servicemen and women - support British interests and promote his own charities.
Earlier Prince Harry's support of a landmine clearance charity was praised when he visited an exhibition highlighting the organisation's work.
The Prince made the trip to Capitol Hill in Washington to see a photographic display aimed at raising awareness about the efforts of the anti-landmine charity the Halo Trust.
Fiona Willoughby, wife of Halo's CEO Guy Willoughby, took many of the pictures displayed at the exhibition.
Mrs Willoughby said:
Having Prince Harry attend our exhibition makes it a global issue.
People have forgotten about it and we think Prince Harry following in his mother's footsteps is a worthy cause and will raise the profile of what we are doing.
He's a soldier he's been to Afghanistan so he understands landmines, he understands conflict and the landmine clearance that's need.
