Katy’s sibling Angela guffawed with glee when she managed to overcome her famous relative in a game of button bashing, which ended with a generous dollop full of whipped cream being launched towards her face.
And when the toy failed to deliver its payload she took matters into her own hands, then giving her sibling a messy facial.
In her Instagram posting Katy explained what her festive get together was like, saying that her family is having a peaceful holiday with her boyfriend.
But while she lost out fair and square, the “California Gurls” singer proved to be a bad sport, getting a dollop of her own and splatting it over her sister.
Katy also shared video from Tokyo’s Sanrio Puroland theme park as she and Orlando Bloom watched a parade that included a Hello Kitty float.
She posted on Instagram that Orlando was quite embarrassed but he should be proud and be man enough, obviously referring to being on the Hello Kitty float.
The actor later uploaded a snap with a geisha girl, smiling coyly at the camera as he bowed to her. He captioned the photo ‘Arigatōgozaimashita’ which is a general way of saying thank you in Japan.
