Prince Alexander, Duke of Södermanland was as good as gold during his star-studded christening at Drottningholm Palace Church in Sweden today (9 September).

The fifth-in-line to the throne – who was born in April – debuted his cherubic face and angelic behaviour during the traditional ceremony. The five-month-old prince wore the same christening gown worn by Prince Gustaf Adolf in 1906 as his mother, Princess Sofia, carried him into the church.

Sofia Hellqvist, Duchess of Värmland, looked groomed to perfection in a beautiful two-piece custom made white lace outfit by Ida Sjöstedt.

The 31-year-old styled her elegant look with a statement pearl headband while keeping her hair tied back in her trademark, slick updo. She finished off the look with cream satin heels and couldn't stop smiling as she proudly beheld her firstborn christened by Archbishop Antje Jackelen.

Sofia – a former glamour model and reality television presenter – was accompanied by her handsome husband of one year, 37-year-old Prince Carl Philip. The prince looked as dashing as ever, clad in his full naval uniform. He was appointed kapten in the Swedish Navy and achieved the rank of major in 2014.

The service, which was attended by other Swedish royals, politicians and glamorous guests, is being aired for the nation by SVT and was followed by a reception and lunch for VIPs at the picturesque Drottningholm Palace – the private residence of the Swedish royal family, originally built in the late 16<sup>th century.

King Carl XVI Gustaf and Queen Silvia were also in attendance and were seated next to Sofia's parents, completing the royal party. Sofia's two sisters also attended the event and her sibling Lina – who is godmother to Prince Alexander – delivered a reading during the service.

Baby Alexander was baptised using water from a spring on the island of Öland, which is a long-standing tradition. His parents and godparents stood nearby as he was blessed at the font.
