Monaco's march for climate change on Sunday (Nov. 29) had two adorable little royal participants. Prince Albert and Princess Charlene's twins, Prince Jacques and Princess Gabriella, joined their parents at the peaceful demonstration in the streets of the principality. The Monegasque sovereign has revealed that he has been sharing his love of sport with his children and now the royal couple are helping the twins get a head start on understanding topics close to their hearts.

Bundled up against the cold, the twins joined demonstrators at the event ahead of a meeting of world leaders in Paris to try to reach a pact on climate change.

Charlene, 37, a former Olympic swimmer, stopped regularly to hug other children on the march.

Albert, 57, showed that he is a hands on father, too, checking every now and then on Jacques and Gabriella, who will turn one on Dec. 10. It's easy to tell them apart because the royals helpfully give them different coloured dummies – blue for Jacques and pink for Gabriella.

Before that the royal babies joined their parents at a traditional picnic over the summer. Prince Albert recently revealed that Jacques and Gabriella are starting to take their first steps and trying to speak.

"They are beginning to take their first steps and trying to say little bits of words," Albert told Monaco Matin. "They really want to express themselves and I speak to them in French. In everyday life, they are very playful and curious."
