Tallulah Willis is feeling 22!
Demi Moore and Bruce Willis' youngest daughter rang in her birthday Wednesday surrounded by family, which included her mom and older sisters, 27-year-old Rumer and 24-year-old Scout.
The birthday girl posted several photos to Instagram, including one absolutely adorable snap that showered her mother with appreciation -- both in the caption and photo itself, which shows Tallulah cradling her mom.
"Thanks for holding me in your body for 9 months bb," Tallulah wrote.
Tallulah also shared a video from her birthday bash -- apparently she channeled her inner Britney Spears during karaoke!
Scout sang as well, opting to perform a different pop hit from the same era, LeAnn Rimes' "Can't Fight the Moonlight."
The cutest of all may have been when the family joined in on a rendition of "Lady Marmalade," though!
Following the festivities, Rumer shared a sweet group photo from the family's night out.
"Love these beautiful humans so much," she wrote. "Couldn't ask for a better group of women to call my fam. Celebrating the birth of my baby girl @buuski I love you guys so much #famovereverything."
This isn't the first time the family has shown support for one another. Watch the video below to hear Rumer talk about the importance of sticking together following a tragic event that occurred at their family home over the summer.
