Jake Gyllenhaal is a family man
The actor is besotted with sister Maggie Gyllenhaal's two daughters, Ramona, six, and three-month-old Gloria, and describes the girls as "extraordinary".
He added: "They are the best thing that happened to my family probably ever."
Jake Gyllenhaal, 31, admits he can see similarities between Ramona and Gloria and him and 34-year-old Maggie when they were growing up.
He told 'Anderson Live': "It's a similar dynamic between me and my sister to this day. I think we are each other's toughest critics, but we also, I think, love each other's work more than anyone else.
"Even at this age, my older niece will come up to her [sister] and joke to her, and she'll laugh and then she'll run away and she starts to cry."
Jake Gyllenhaal recently joked he was a "troubled uncle", saying: "I play a troubled uncle (in new movie 'End of Watch'), which is not dissimilar to my real life! I have a three-month-old niece and a six-year-old niece."
