On Tuesday, the 21-year-old took to Instagram to not only send a shout out to her big sis, but to flaunt her killer bod as well (above).
The brunette beauty was certainly in the partying mood.
She jokingly wrote:
"Still from Scouts upcoming directorial debut. A short film entitled 'BUUSKI'. stay classy kids 😉🎩🐪"
Fierce! Does that mean there are more pics to come?!
Nonetheless, the celebutante didn't forget that the night was about Rumer's big win.

AH-Mazing! However, Tallulah's desire to show some skin was a theme throughout the course of the day.
Prior to the DWTS finale, she shared:

LOLz! Girl loves to take her clothes off!
Remember when Miley Cyrus and the younger Willis sisters took partially-nekkid pics for Instagram?! We certainly do!
You keep doing you, Tallulah! But maybe let your sister have the spotlight for a little bit longer — she did just win a reality show!
