They looked like any other happy young couple as they set off on foot for the christening of the newest addition to their family with their young son in tow.

Except for the fact that this was a very royal christening of a Princess.

The Duke and Duchess of Cambridge and Prince George were joined by the Queen and Prince Phillip and 21 official guests for Princess Charlotte's christening at the church of St Mary Magdalene in Sandringham.

It was the first glimpse of Charlotte since her birth in May and the second time she has been seen in public.

It was also a rare opportunity to see the growing family together in public for the first time.

New mum Kate looked as elegant as ever in an ivory Alexander McQueen outfit with Jane Taylor hat as she pushed Charlotte in a traditional-style black pram while George walked alongside his parents. The toddler wore red shorts and a white embroidered shirt reminiscent of the outfit worn by a young Prince William when he went to visit his newborn brother Prince Harry.

Clutching his father's hand tightly curious George couldn't help peer into the pram at his sister as the family gathered ahead of the ceremony.

As the family and guests prepared to enter the church Kate lifted the Princess from her pram and settled her gently as she started to cry.

Charlotte's five godparents followed among them Adam Middleton, the duchess's cousin, and the Honourable Laura Fellowes, 35 , a niece of Princess Diana.

The princess was christened in a short private service conducted by the Archbishop of Canterbury, the Right Rev Justin Welby, supported by the Reverend Canon Jonathan Riviere, the rector of the Sandringham group of parishes.

Princess Diana's memory was honoured as they chose Charlotte's middle names, Elizabeth Diana. It was also at the same church that Diana was christened in 1961.

During the service, members of the coronation sang two hymns chosen by William and Kate, Praise to the Lord, The Almighty and Come Down, O Love Divine while the Sandringham Church Choir performed for the occasion.

The royal couple later hosted a tea for Charlotte and fellow christening guests at the main house at the family's Sandringham estate.

The Princess was born on the morning of 2 May, in the Lindo wing of St Mary's hospital, Where Prince George was also born. She arrived at 8.34am, weighing 8lb 3oz. An official announcement about the birth came just after 11.15am after the couple had informed their respective families.

She is fourth-in-line to the British throne after her grandfather, Prince Charles, her father Prince William and brother Prince George, who is almost two years old.
