Cute panties! Rumer Willis wore a risque ensemble to the Elle Women in Music celebration on Tuesday, April 22, showing off more than she intended.
The 25-year-old -- who DJ'd a set at the event -- paired a black crop top with the "Isabella Square" skirt by Franziska Fox that featured large side-panel cutouts. While Bruce Willis and Demi Moore's daughter surely meant to flash her long legs, we can't imagine that fearless attitude extended to her pink underwear that peeked through.
The surprise panties exposure stole the thunder of another big change the star recently made: The natural brunette debuted a new ginger hair color.
An insider tells Us Weekly the Hollywood scion hopped onstage during the celebration and played a range of hits, from TLC's "Waterfalls" to Carly Simon's "You're So Vain." She "danced a bit" to Beyonce and Jay Z's "Drunk In Love," too.
Willis wasn't the only celeb to hit up the event in sexy, skin-baring looks. Sophia Bush opted for a white crop top ensemble and pregnant Stacy Keibler cradled her burgeoning bump in a black gown with cutouts at her waist.
Most recently, Willis has also been generating buzz over her impressive work in the theatrical show, For the Record: Tarantino. The young star recently performed at West Hollywood hotspot DBA, where a brief family reunion (of sorts) took place: Both mom Moore and papa Willis were in the house to support their eldest daughter. "They stayed after to congratulate her and chat for a bit," an eyewitness told Us. "Bruce and Demi did not interact with each other."
