Nobel prize-giving ceremonies in Norway and Sweden saw the royal families from both countries turn out for the annual event.
All eyes were on the younger royals, with Crown Prince Haakon, joined by his mother Queen Sonja and pregnant wife Crown Princess Mette-Marit, stepping in to take the place of his ill father King Harald at the peace prize ceremony in Oslo. Meanwhile, in Stockholm, Crown Princess Victoria and her sister Princess Madeleine were stunning in full length gowns and glittering tiaras as they attended a special banquet with their parents in honour of recipients of the medicine, physics, chemistry, literature and economics awards.
However, it wasn't just the pretty young royals who added a touch of glamour to the momentous occasion. Catherine Zeta-Jones and her husband Michael Douglas brought their own brand of style to the Oslo ceremony, where the Hollywood couple were on hand to see Iranian activist Shirin Ebadi accept the 2003 Peace Prize.
The other Nobel winners included South African novelist JM Coetzee, who won the literature prize, as well as three British born scientists. The UK's Peter Mansfield was honoured alongside American Paul Lauterbur in the medicine category, Clive Granger and American Robert Engle jointly took home the economics award, and British-born Anthony Leggett, and Russians Vitaly Ginzburg and Alexei Abrikosov, received a gong for physics.
