Queen Elizabeth II was in attendance today as her great-grandsons August Brooksbank and Lucas Tindall were christened.

The double christening went ahead on the evening of Sunday, Nov. 21. The Queen had been forced to cancel recent events due to health issues, but she was fortunately able to attend the ceremony at All Saints Chapel in Windsor today.

The ceremony was for August Brooksbank, the son of Princess Eugenie and Jack Brooksbank, as well as Lucas Tindall, the son of Zara Phillips and Mike Tindall. Both were born earlier this year and are great-grandsons of the Queen.

So far, photos have only shown members of the Royal Family arriving by car at the ceremony in Windsor. It's unclear how much they plan to share from the private event.

The Queen was said to be "determined" to attend the important religious ceremony despite her recent hospital stay and back injury.

The christening is among Queen Elizabeth's first-known outings since she had to back out of public engagements beginning in late October.

She was expected to attend the Remembrance Sunday service at the Cenotaph last weekend, but she cancelled after a similar last-minute decision.

At that time, the Palace revealed that the Queen has been dealing with a sprained back. But the injury appears to be unrelated to an earlier, unspecified issue that kept the Queen in hospital overnight on Oct. 21.

Before today, the Queen was last seen early in the week when she hosted an audience at Windsor Castle.

Family members including Prince Charles and Sarah Ferguson have also been reassuring fans that the Queen is doing well despite her health troubles.

The Queen's family was surely thrilled to have her at the ceremony today for 9-month-old August Brooksbank and 8-month-old Lucas Tindall.
