It looks like it's getting busier and livelier at the home of four-time F1 world champion Max Verstappen and his girlfriend Kelly Piquet.

The Brazilian regularly shares glimpses of her home life on her Instagram page and has now appeared to reveal two new arrivals in the family.

With young daughters Penelope and Lily to look after, it’s understandably a busy house for Max and Kelly, but that has not stopped them from getting several pets over the last few years.

The couple have three cats - Jimmy, Sassy and Donatello - and a Dachshund, Nino, and Kelly has now appeared to confirm two new arrivals.

In one post, Piquet shared a picture of a cat and her daughter Lily to her Instagram story, captioning it: 'New addition to the family.' Then, in a second story, she shared a photo of a dog with the caption, 'Officially outnumbered by the animals in the house.'

At this stage, their names are unconfirmed.

Verstappen frustrated after Red Bull 'disaster' in Brazil

Arriving home to new pets should cheer Verstappen up after a frustrating afternoon for him in damp conditions in Sao Paulo on Sunday.

Despite starting in P21 due to an engine penalty, the four-time world champion put on a strong performance to work his way onto the podium and secure P2 come the chequered flag.

Post-race, however, he was furious with his team and the car that he had underneath him in Brazil.

“My God, doing 85% of the race with a f****d car," Verstappen told his team over the radio.

"Of course, P2 is nice, but not in this way. I’m sorry, but what a disaster to drive. Unbelievable!

"I've never experienced anything like this in the wet or the dry, really, really bad."

Verstappen and the rest of the F1 grid now have a weekend off, with the Las Vegas Grand Prix set to take place from November 19-21.
