Princess Charlene publicly supported her husband, Prince Albert of Monaco, as the royals attended a mass in memory of Albert's late father, Prince Rainier III, on Wednesday.
The couple were pictured holding hands as they arrived at the cathedral, where they were also joined by Albert's sisters, Princess Caroline of Hanover and Princess Stephanie.
Charlene, 45, who was dressed in a sombre black and grey ensemble, also embraced Albert's niece, Charlotte Casiraghi, upon arrival.
Thursday marks the 18th anniversary of Prince Rainier's death, who passed away at the age of 81 on 6 April 2005 after complications relating to a lung infection. He was buried on 15 April 2005 beside his wife, Princess Grace, at the Cathedral of Our Lady Immaculate.
Prince Albert, now 65, succeeded his father as Prince of Monaco, with his enthronement taking place three months after his father's death.
