Ah, sisters. So much love … and so much drama!
“They are so lovely, they are such great friends and they love each other so much,” the How I Met Your Mother actress, 41, tells PEOPLE. “Obviously they have their moments where they need space or a nap. But they really are just such good friends and they’re so funny.”
Recently, though, they had a video-worthy moment.
“There was an argument going on that was so cute I had to record it,” Hannigan recalls. “It started with Saty wanting to play with Keeva, and Keeva wanted to have some alone playtime. And it got to a point where they’re both crying, and Saty is like, ‘But I want to play with you!’ And Keeva’s like, ‘But I want alone time!’ And it was just such a cute argument that I’m like, I’ve got to record this because they need to see it in 10 years.”
