It's anything but a dispiriting holiday season for the Button household with Jenson and partner Brittny Ward welcoming their second child over the Christmas weekend.

The 2009 F1 world champion and the proud father of Hendrix, who is 17-months-old, announced on social media the most precious of gifts delivered by Santa in Los Angeles.

"Welcome Lenny Monrow Button 😍 Mummy & Daddy are besotted already," wrote Jenson.

"She has the cutest little dimples like her big brother Hendrix 😊 Britt is doing amazing and recovering well."

And among the first to congratulate the couple on the new family addition was none other than Danny Ric!
