Prince George and Princess Charlotte usually give handmade gifts to the Queen on her birthday

Prince George and Princess Charlotte surely had a blast celebrating their great-grandmother's birthday over the weekend, as the monarch turned 92.

The royal family celebrated the big day on Saturday at the Queen’s Birthday Party at the Royal Albert Hall, which included performances from the likes of Tom Jones, Kylie Minogue, and Sting, and saw Harry and Meghan in the crowd.

Prince William also joined to wish his grandmother a happy birthday, but his wife Kate Middleton, who's due to give birth to their third child any moment now, stayed home, as did Prince George and Princess Charlotte.

But even though Kate and William's little ones didn't get to attend the big birthday bash, it seems they have still given her the perfect gift.

According to their dad, William, the tiny royals usually make their own gifts for the Queen's birthday, which apparently the monarch really enjoys.

During an interview on BBC Radio 1, when asked what they gift the Queen on her birthday, William admitted that he's tried to make presents himself before but now leaves the personalised gifts to his kids.

'It's quite hard to know what to get the Queen for her 91st birthday that she hasn’t already got!', he said.

When Kate reminded him that he's 'very good at making things', he added: 'We've tried making a few things. With the great-grandchildren around of course they can make stuff and that goes down very well.'

The Queen turned 92 this weekend

The dad continued to say that they now stick to handmade presents as the Queen enjoys receiving them, no matter what they look like.

'Doesn't matter what it looks like, it just goes down really well. We stick to those sorts of presents', he said. 'George does [arts and crafts], he's very good at it.'

But we bet whatever George and Charlotte make for their great-grandmother looks lovely, as both tots attend schools that place equal value in expressive arts and design as the rest of their subjects.

And now with another great-grandchild on the way, the Queen has even more cute handmade gifts to look forward to!
