4-year-old Princess Leonore proved a handful at little sister's christening

Princess Leonore of Sweden felt so at home inside a church during her baby sister's christening that she rolled on the floor in the middle of the church service.

Daily News posted a video on YouTube showing the four-year-old royal having too much fun during the christening of her baby sister, Princess Adrienne.

Seemingly bored, Princess Leonore walked to the center of the aisle and rolled in her white dress, in plain view of the three priests presiding the ceremony.

Princess Leonore is the daughter of Princess Madeleine and her husband, Christopher O'Neill.

Princess Madeleine looked exasperated as she holds three-month-old Adrienne in her arms. She could not stand to get her misbehaving daughter.

A social media post captured Princess Madeleine as she shoots a fierce look at her daughter lying on her back on the aisle.

Twitter user Craig shares such a photo and wrote: 'This clip has made my day! Princess Leonore of Sweden rolling round at her sibling's christening. Princess Madeleine's face is priceless.'

Aside from Leonore and Adrienne, Princess Madeleine and her husband also have a son, Prince Nicolas.

Madeleine, who married the American-British financier Christopher O'Neill in 2013, is the youngest of King Carl XVI Gustaf and Queen Silvia's three children.

Photos from Princess Adrienne's christening also show Leonore seeming to choke her two-year-old brother.

Twitter user Kruunun Vartija wrote: 'I think Princess Leonore of Sweden will change the monarchies more than Meghan Markle.'

Both Leonore and her brother Nicolas were noticeably absent from a family photo taken after the christening.

Princess Madeleine shared the photo on her Instagram account.

For displaying her adorable antics in public, Princess Leonore joins the ranks of Britain's Princess Charlotte and Prince George. Prince William and Kate Middleton's children have also caught people's attention for showing their silly side during major royal events.

For instance, Princess Charlotte was photographed sticking her tongue out as she arrived at the church where her uncle, Prince Harry, was to tie the knot with former American actress Meghan Markle.
