Elizabeth Olsen on The Tonight Show still

Growing up the younger sister of Mary-Kate and Ashley Olsen meant Elizabeth Olsen didn't exactly have the average childhood.

The "Avengers: Infinity War" star was promoting her upcoming web series "Sorry for Your Loss" on "The Tonight Show" on Sept. 7 when host Jimmy Fallon asked her about having roles in Mary-Kate and Ashley projects as a kid. Her older sisters made about 60 videos, Olsen said, and it turns out that her appearances in them were "like after-school care" for her. When your sisters are entertainment moguls, making cameos in music videos is apparently not out of the norm.

Of course, Fallon didn't let Olsen escape a throwback to her childhood. The late-night TV host showed a clip from the video "B-U-T-T Out," which shows Olsen pouting as her big sisters sing about how she can't tag along with them. Poor girl.

Olsen told Fallon that she only vaguely remembers filming her parts. Although she has seen them, she doesn't really recall "the experience of doing it." Luckily for her, the videos will be around forever.

Watch below, starting around 3:42.



"Sorry for Your Loss" premieres Sept. 18 on Facebook Watch; "The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET/PT on NBC.
