The Willis sisters have been blowing up due to their recent group bikini shot, but they uploaded a much more revealing photo in days before.
The sisters each cover their chests with their knees, with Tallulah, 23, also shown eating an ice cream.
Tallulah simply captioned the post, which has received 13,000 likes, with three angel emojis.
While there were some detractors, most of the comments were kind and admired the sisters' closeness to one another.
"Really sweet you all can be together like that," one user wrote.
Another added, "Talk about quality fam time."
Tallulah also shared the viral photo of herself, 26-year-old-Scout and 29-year-old Rumer swimming in an ice cold river just before Christmas.
