London:  Duchess of Cambridge on Sunday released pictures of her daughter Princess Charlotte, to mark her six-month milestone.

The two official images are the first to be released of the fourth-in-line to the British throne since her christening in July.

They were released by the Duke and Duchess of Cambridge via their Kensington Palace office to thank fans for the good wishes sent to the royal couple.

The photographs were taken by Kate at their family home Anmer Hall in Norfolk in the east of England early in November.

Kate is an accomplished amateur photographer and took a joint portrait of her children Prince George, aged two, and Charlotte a few weeks after her daughter was born on 2 May, reports NDTV news.

The last time the princess was seen in public was in July during her christening at St Mary Magdalene Church on the Queen’s Sandringham Estate in Norfolk.

In the first picture released, Charlotte is seen to now have a full head of hair as she sits in a chair with her toy, the Sunday Telegraph reported.

She howls with laughter as her mother snaps away with the camera—believed to be the same Canon EOS 5D Mark II she used for previous shots of her children.

In the second image, the princess is shown looking past the camera as if something has caught her attention behind the Duchess.

Charlotte is seen to be wearing a pink cashmere cardigan over a print dress with a frilly collar.

They once again show Kate’s ability behind the camera as the first official pictures of Charlotte—taken when she was just a fortnight old and alongside her brother —were also captured by her and released in June.

The royal baby was christened by the Archbishop of Canterbury on 5 July in the church of St Mary Magdalene, Sandringham, close to Anmer Hall.

The service was private, but photographs taken by Mario Testino were released to the media afterwards.
