Kristen: How was your weekend, Maya?
Maya: It was great! My boyfriend and I went skiing.
Jennifer: My boyfriend, who's a model....took me skiing for two months in the Alps last year and he's taking me to the North Pole this Christmas to meet Santa Claus.
Kristen rolling her eyes and whispering to Maya..."She is such a Penelope!"
